What makes us like music? Determinants of music preference.

What are the determinants of music preference, and how strong is their relative influence? This article investigates the parameters that may influence music preference, focusing on the cognitive, emotional, and cultural functions of music, physiological arousal, and familiarity. Data were collected in a lab study and in an online survey (total N = 263). Participants listened to six pieces of distinct musical styles (and to their own favorite music in the lab study). They had to indicate how much they liked the music and how much they agreed with a list of statements concerning the parameters mentioned above for each piece. Multiple regressions revealed that all parameters (except cultural functions) accounted significantly for the strength of music preference. The cognitive functions of music (i.e., music as a means for communication and self-reflection), as well as physiological arousal elicited by the music, were the most important determinants of music preference. The results are discussed in the light of several assumptions about the evolutionary foundation of music listening. In addition, the present findings may serve as a basis for the construction of an empirically derived theory of music preference. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sex and gender in the college classroom: A quantitative analysis of faculty–student interactions and perceptions.

Students and instructors from 24 classrooms across 8 departments at a major university were observed in this study to (a) assess for sex differences in faculty–student interactions and in students' perceptions of their college classroom environment, (b) compare student perceptions of their college classroom interaction patterns with observed faculty–student interactions, and (c) assess a variety of demographic characteristics together to determine their singular and/or interactive effects on faculty–student interaction patterns and student perceptions. Male and female students did not differ in their classroom participation or perceptions, and instructors did not interact differently with the male and female students. Student perceptions strongly correlated with their own behaviors and with instructor behaviors. Classroom interactions and student perceptions varied on the basis of different demographic characteristics including instructor sex, class size, instructor monitoring of gender–race equity in the classroom, gender relevance of the course, and the sex ratio of the class.

Cultural similarities and differences in group work: Pilot study of a U.S.–Chinese group comparison.

This pilot study representing collaborative cross-cultural research was conducted to compare cross-cultural similarities and differences between 2 comparable task groups by using the 8-step learning through discussion (LTD; W. F. Hill, 1969) method. One LTD group was conducted in the United States with U.S. members; the other LTD group was conducted in China with Chinese members. The same scholarly article on career needs of Chinese middle school students provided the discussion input (M. H. France, Y. Jin, K. Huang, F. Si, & W. Zhang, 1991). Videotapes of each group were made for comparative review by the researchers, providing for analysis of similarities and differences in verbal interaction, nonverbal interaction, leader role, and content themes. Implications of the results and suggestions for U.S. group leaders in working with Chinese task groups are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Randomized controlled trial of a cognitive–behavioral motivational intervention in a group versus individual format for substance use disorders.

Although group therapy is widely used for individuals with substance use disorders (SUDs), randomized clinical trials (RCTs) comparing the same treatment in a group versus individual format are rare. This paper presents the results of a RCT comparing guided self-change (GSC) treatment, a cognitive–behavioral motivational intervention, conducted in a group versus individual format with 212 alcohol abusers and 52 drug abusers who voluntarily sought outpatient treatment. Treatment outcomes demonstrated significant and large reductions in clients’ alcohol and drug use during treatment and at the 12-month follow-up, with no significant differences between the group and individual therapy conditions. A therapist time ratio analysis found that it took 41.4% less therapist time to treat clients using the group versus the individual format. Participants’ end-of-treatment group cohesion scores characterized the groups as having high engagement, low levels of interpersonal conflict, and low avoidance of group work, all desirable group characteristics. These findings suggest that the GSC treatment model was effectively integrated into a brief group treatment format. Health care cost containment compels further evaluations of the efficacy of group treatments for SUDs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Can implementation intentions and text messages promote brisk walking? A randomized trial.

Objective: To test the efficacy in promoting brisk walking of two theory-based interventions that incorporate implementation intentions and text message (Short Message Service; SMS) reminders directed at one’s walking-related plans or goals. Design: Participants (N = 149) were randomized to one of three conditions (implementation intention + SMS plan reminder, implementation intention + SMS goal reminder, control) before completing measures at baseline and follow-up 4 weeks later. At follow-up, the experimental groups were given a surprise recall task concerning their plans. All participants completed an equivalent goal recall task. Main Outcome Measures: Validated self-report measures of physical activity and measures of implementation intention and goal recall, weight, and waist-to-hip ratio. Results: Both intervention groups increased their brisk walking relative to the control group, without reducing other physical activity. The goal reminder group lost the most weight. The SMS plan reminder group recalled more of their plans than the SMS goal reminder group, but the latter were more successful in goal recall. Conclusion: Both interventions can promote brisk walking in sedentary populations. Text messages aid the recall of, and could enhance interventions that target, implementation intentions and goals.

How and for whom are decision aids effective? Long-term psychological outcome of a randomized controlled trial in women with newly diagnosed breast cancer.

Objective: The current study evaluates the long-term psychological impact of a decision aid intervention for surgical and systemic treatment in women with newly diagnosed breast cancer from a previous reported randomized, controlled trial (Vodermaier et al., 2009). Methods: Patients (n = 111) were randomized into usual care, or a 20-min decision aid intervention plus an information brochure prior to consultation planning with the senior physician. The retention rate at 1 year was 88%. Results: Linear mixed model analyses demonstrated that the intervention group experienced less decisional conflict (p = .047; d = .19), which was driven by perceptions of a more effective choice (p = .029; d = .20) over time. Subgroup analyses revealed that patients in the intervention group who participated in chemotherapy decision making showed better long-term body image outcomes (p = .009; d = .44), which were mediated by reduced depressive coping (p = .049). No effects emerged for anxiety and depressive symptoms, or for quality of life. Internal health locus of control moderated group effects on 'uncertainty with the decision' (p = .003). Conclusions: The study results provide novel evidence on the role of individual differences and the mechanisms behind decision aid effectiveness, and demonstrate the long-term impact of decision aid interventions on some indices of well-being.

Psychotherapy in two-plus-one sessions: Outcomes of a randomized controlled trial of cognitive–behavioral and psychodynamic–interpersonal therapy for subsyndromal depression.

A total of 116 clients with a range of subsyndromal depression received 3 therapy sessions: 2 sessions 1 week apart followed by a 3rd session 3 months later (the 2?+?1 model). Clients were stratified for severity on the Beck Depression Inventory (BDI) as stressed, subclinical, or low-level clinically depressed. In a 2?×?2 design, they received either cognitive–behavioral (CB) or psychodynamic–interpersonal (PI) therapy, either immediately or after a 4-week delay. An initial advantage for the immediate condition disappeared once the delayed-condition clients received treatment. Improvement rates at the end of treatment were 67% (stressed), 72% (subclinical), and 65% (low-level clinically depressed). There were no significant differences between CB and PI treatment methods, with the exception at 1-year follow-up, when the BDI showed a significant advantage for CB. Implications for designing very brief planned interventions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Which survey questions change behavior? Randomized controlled trial of mere measurement interventions.

Objective: Evidence indicates that receiving a questionnaire about a behavior increases the likelihood that the person will perform that behavior—a phenomenon termed the mere measurement effect. This research tested the role of (a) the type of questions, and (b) questionnaire completion in optimizing the impact of mere measurement interventions designed to retain novice blood donors. Design: Novice blood donors (N = 4391) were randomly allocated to four conditions that varied the content of a questionnaire about blood donation (behavioral intention-only, behavioral intention plus regret, implementation intention-only, implementation intention plus regret) or to a no-questionnaire control condition. Main Outcome Measures: Objective measures of registration at blood drives were obtained at 6 and 12 months postbaseline. Results: Participants in the implementation intention-only condition donated more frequently at 6 months compared to participants in each of the other conditions. At 12 months both implementation intention conditions outperformed the other conditions. Implementation intentions increased the frequency of donations over 1 year by 12%. Measuring anticipated regret did not augment the impact of interventions whereas questionnaire completion had an important impact on donation behavior. Conclusion: Questions about implementation intentions but not behavioral intentions promote retention of novice blood donors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

How does tele-mental health affect group therapy process? Secondary analysis of a noninferiority trial.

Objective: Video teleconferencing (VTC) is used for mental health treatment delivery to geographically remote, underserved populations. However, few studies have examined how VTC affects individual or group psychotherapy processes. This study compares process variables such as therapeutic alliance and attrition among participants receiving anger management group therapy either through traditional face-to-face delivery or by VTC. Method: The current study represents secondary analyses of a randomized noninferiority trial (Morland et al., in press) in which clinical effectiveness of VTC delivery proved noninferior to in-person delivery. Participants were male veterans (N = 112) with posttraumatic stress disorder (PTSD) and moderate to severe anger problems. The present study examined potential differences in process variables, including therapeutic alliance, satisfaction, treatment credibility, attendance, homework completion, and attrition. Results: No significant differences were found between the two modalities on most process variables. However, individuals in the VTC condition exhibited lower alliance with the group leader than those in the in-person condition. Mean self–leader alliance scores were 4.2 (SD = 0.8) and 4.5 (SD = 0.4), respectively, where 5 represents strongly agree and 4 represents agree with positive statements about the relationship, suggesting that participants in both conditions felt reasonably strong alliance in absolute terms. Individuals who had stronger alliance tended to have better anger outcomes, yet the effect was not strong enough to result in the VTC condition producing inferior aggregate outcomes. Conclusion: Our findings suggest that even if group psychotherapy via VTC differs in subtle ways from in-person delivery, VTC is a viable and effective means of delivering psychotherapy.

What develops in working memory? A life span perspective.

This study investigated whether working-memory (WM) span differences across age are attributable to specific or general processing functions. The study compared 9 age groups (6, 8, 10, 13, 16, 24, 35, 45, 57 years) on verbal and visuospatial WM performance under initial (no probes or cues), gain (cues that bring performance to an asymptotic level), and maintenance conditions (asymptotic conditions without cues). (a) Age-related performance differences in WM were found across all conditions and were not isolated to specific processes, (b) significant performance differences remained among age groups on gain and maintenance conditions, and (c) the gain (accessing new information) and maintenance conditions (maintenance of old information) for verbal and visuospatial WM tasks contributed independent variance to age-related performance. The results support a general capacity explanation of age-related differences. These differences in capacity reflect demands placed on both the accessing of new information and the maintenance of old information.

Chronic low-back pain: What does cognitive coping skills training add to operant behavioral treatment? Results of a randomized clinical trial.

This study examined the supplemental value of a cognitive coping skills training when added to an operant-behavioral treatment for chronic low-back pain patients. The complete treatment package (OPCO) was compared with an operant program?+?group discussion (OPDI) and a waiting-list control (WLC). After the WL period, the WLC patients received a less protocolized operant program usually provided in Dutch rehabilitation centers (OPUS). Regression analyses showed that, compared with WLC, both OPCO and OPDI led to less negative affect, higher activity tolerance, less pain behavior, and higher pain coping and pain control. At posttreatment, OPCO led to better pain coping and pain control than OPDI. Calculation of improvement rates revealed that OPCO and OPDI had significantly more improved patients than OPUS on all the dependent variables. The discussion includes findings regarding treatment credibility, compliance, and contamination bias. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What is the latent structure of alcohol use disorders? A taxometric analysis of the Personality Assessment Inventory Alcohol Problems Scale in male and female prison inmates.

Three indicators derived from the Personality Assessment Inventory (PAI) Alcohol Problems scale (ALC)—tolerance/high consumption, loss of control, and negative social and psychological consequences—were subjected to taxometric analysis—mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent mode factor analysis (L-Mode)—in 1,374 federal prison inmates (905 males, 469 females). Whereas the total sample yielded ambiguous results, the male subsample produced dimensional results, and the female subsample produced taxonic results. Interpreting these findings in light of previous taxometric research on alcohol abuse and dependence it is speculated that while alcohol use disorders may be taxonic in female offenders, they are probably both taxonic and dimensional in male offenders. Two models of male alcohol use disorder in males are considered, one in which the diagnostic features are categorical and the severity of symptomatology is dimensional, and one in which some diagnostic features (e.g., withdrawal) are taxonic and other features (e.g., social problems) are dimensional.

What are the benefits of mindfulness? A practice review of psychotherapy-related research.

Research suggests that mindfulness practices offer psychotherapists a way to positively affect aspects of therapy that account for successful treatment. This paper provides psychotherapists with a synthesis of the empirically supported advantages of mindfulness. Definitions of mindfulness and evidence-based interpersonal, affective, and intrapersonal benefits of mindfulness are presented. Research on therapists who meditate and client outcomes of therapists who meditate are reviewed. Implications for practice, research, and training are discussed.

Cognitive–behavioral therapy, behavioral weight loss, and sequential treatment for obese patients with binge-eating disorder: A randomized controlled trial.

Objective: Cognitive–behavioral therapy (CBT) is the best established treatment for binge-eating disorder (BED) but does not produce weight loss. The efficacy of behavioral weight loss (BWL) in obese patients with BED is uncertain. This study compared CBT, BWL, and a sequential approach in which CBT is delivered first, followed by BWL (CBT + BWL). Method: 125 obese patients with BED were randomly assigned to 1 of the 3 manualized treatments delivered in groups. Independent assessments were performed posttreatment and at 6- and 12-month follow-ups. Results: At 12-month follow-up, intent-to-treat binge-eating remission rates were 51% (CBT), 36% (BWL), and 40% (CBT + BWL), and mean percent BMI losses were ?0.9, ?2.1, and 1.5, respectively. Mixed-models analyses revealed that CBT produced significantly greater reductions in binge eating than BWL through 12-month follow-up and that BWL produced significantly greater percent BMI loss during treatment. The overall significant percent BMI loss in CBT + BWL was attributable to the significant effects during the BWL component. Binge-eating remission at major assessment points was associated significantly with greater percent BMI loss cross-sectionally and prospectively (i.e., at subsequent follow-ups). Conclusions: CBT was superior to BWL for producing reductions in binge eating through 12-month follow-up, while BWL produced statistically greater, albeit modest, weight losses during treatment. Results do not support the utility of the sequential approach of providing BWL following CBT. Remission from binge eating was associated with significantly greater percent BMI loss. Findings support BWL as an alternative treatment option to CBT for BED. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Does group climate mediate the group leadership–group member outcome relationship?: A test of Yalom's hypotheses about leadership priorities.

I. D. Yalom's (1995) hypothesis that group climate mediates the relationship between leadership and outcome was tested. Group leaders (N?=?43) recorded intentions, and adolescent group members (N?=?233) rated climate after 8 semistructured group sessions. Members also rated satisfaction at termination. Leader intentions comprised 4 dimensions: therapeutic work, safe environment, interpersonal, and group structure. Changing group climates did mediate between these intentions and member outcome. Therapeutic work was negatively related and safe environment was positively related to an increasingly active and engaged climate, which was related to treatment benefit. Group structure and possibly interpersonal intentions were related to a climate decreasing in conflict and distance, which was related to a positive leader relationship. The importance of leaders focusing on group process rather than individual change is highlighted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Did lifetime rates of alcohol use disorders increase by 67% in 10 years? A comparison of NLAES and NESARC.

Two nationally representative epidemiological samples (the National Longitudinal Alcohol Epidemiological Survey and the National Epidemiological Survey of Alcohol and Related Conditions) have been used to track changes in the prevalence of alcohol use disorders (AUDs) between 1992 and 2002 in the United States. Strikingly, estimates from these two data sets suggest that the lifetime prevalence of AUD increased by approximately 67% (from 18.2% to 30.3%) during this time frame. This article explores potential reasons for these discrepant estimates. Analyses indicated that a vast majority of change in lifetime AUD occurred with respect to alcohol abuse and not alcohol dependence. Most of this increase in abuse was attributable to self-reported changes in hazardous use that did not track with other archival measures of outcomes related to hazardous use in the population. Key methodological differences regarding the frequency requirements for prior-to-past-year alcohol abuse appeared to explain most of the discrepancy in lifetime AUD estimates. These findings, in conjunction with the relative lack of differences in the 12-month prevalence of AUDs, suggest that the discrepant lifetime estimates are likely due to methodological differences between the two surveys. These findings have important implications for substance use and other psychiatric surveillance and epidemiology where meaningful cross-temporal comparisons are desired.

A combined motivation and parent–child interaction therapy package reduces child welfare recidivism in a randomized dismantling field trial.

Objective: A package of parent–child interaction therapy (PCIT) combined with a self-motivational (SM) orientation previously was found in a laboratory trial to reduce child abuse recidivism compared with services as usual (SAU). Objectives of the present study were to test effectiveness in a field agency rather than in a laboratory setting and to dismantle the SM versus SAU orientation and PCIT versus SAU parenting component effects. Method: Participants were 192 parents in child welfare with an average of 6 prior referrals and most with all of their children removed. Following a 2 × 2 sequentially randomized experimental design, parents were randomized first to orientation condition (SM vs. SAU) and then subsequently randomized to a parenting condition (PCIT vs. SAU). Cases were followed for child welfare recidivism for a median of 904 days. An imputation-based approach was used to estimate recidivism survival complicated by significant treatment-related differences in timing and frequency of children returned home. Results: A significant orientation condition by parenting condition interaction favoring the SM + PCIT combination was found for reducing future child welfare reports, and this effect was stronger when children were returned to the home sooner rather than later. Conclusions: Findings demonstrate that previous laboratory results can be replicated in a field implementation setting and among parents with chronic and severe child welfare histories, supporting a synergistic SM + PCIT benefit. Methodological considerations for analyzing child welfare event history data complicated by differential risk deprivation are also emphasized.

Opportunity for interaction? A naturalistic observation study of dual-earner families after work and school.

Everyday patterns of interaction can strengthen or undermine bonds between family members. This naturalistic observation study focused on an understudied facet of family life: opportunities for interaction among dual-earner family members after work and family members’ responses to these opportunities. Thirty dual-earner couples and their children were observed and video-recorded in their homes throughout two weekday afternoons and evenings. Two interaction opportunities were analyzed: (1) the behavior of family members toward a parent returning home from work and (2) the physical proximity of family members throughout the evening. Three main findings emerged. Women, who tended to return home before men, were greeted with positive behavior and reports of the day’s information from family members. Men, in contrast, returned home later in the day and received positive behavior or no acknowledgment from family members distracted by other activities. Throughout the evening, mothers spent more time with children whereas fathers spent more time alone. Couples were seldom together without their children. The implications of observed interaction patterns and the contribution of naturalistic observation methods to the study of family relationships are discussed.

Does distraction reduce the alcohol–aggression relation? A cognitive and behavioral test of the attention-allocation model.

Objective: This study provided the first direct test of the cognitive underpinnings of the attention-allocation model and attempted to replicate and extend past behavioral findings for this model as an explanation for alcohol-related aggression. Method: A diverse community sample (55% African American) of men (N = 159) between 21 and 35 years of age (M = 25.80) were randomly assigned to 1 of 2 beverage conditions (i.e., alcohol, no-alcohol control) and 1 of 2 distraction conditions (i.e., distraction, no-distraction). Following beverage consumption, participants were provoked via reception of electric shocks and a verbal insult from a fictitious male opponent. Participants' attention allocation to aggression words (i.e., aggression bias) and physical aggression were measured using a dot probe task and a shock-based aggression task, respectively. Results: Intoxicated men whose attention was distracted displayed significantly lower levels of aggression bias and enacted significantly less physical aggression than intoxicated men whose attention was not distracted. However, aggression bias did not account for the lower levels of alcohol-related aggression in the distraction, relative to the no-distraction, condition. Conclusions: These results replicated and extended past evidence that cognitive distraction is associated with lower levels of alcohol-related aggression in highly provoked males and provide the first known cognitive data to support the attentional processes posited by the attention-allocation model. Discussion focused on how these data inform intervention programming for alcohol-related aggression. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Results of the “Active by Choice Today” (ACT) randomized trial for increasing physical activity in low-income and minority adolescents.

Objective: This study reports the results of the “Active by Choice Today” (ACT) trial for increasing moderate-to-vigorous physical activity (MVPA) in low-income and minority adolescents. Design: The ACT program was a randomized controlled school-based trial testing the efficacy of a motivational plus behavioral skills intervention on increasing MVPA in underserved adolescents. Twenty-four middle schools were matched on school size, percentage minorities, percentage free or reduce lunch, and urban or rural setting before randomization. A total of 1,563 6th grade students (mean age, 11.3 years, 73% African American, 71% free or reduced lunch, 55% female) participated in either a 17-week (over one academic year) intervention or comparison after-school program. Main Outcome Measure: The primary outcome measure was MVPA based on 7-day accelerometry estimates at 2-weeks postintervention and an intermediate outcome was MVPA at midintervention. Results: At midintervention students in the intervention condition engaged in 4.87 greater minutes of MVPA per day (95% CI: 1.18 to 8.57) than control students. Students in intervention schools engaged in 9.11 min (95% CI: 5.73 to 12.48) more of MVPA per day than those in control schools during the program time periods; indicating a 27 min per week increase in MVPA. No significant effect of the ACT intervention was found outside of school times or for MVPA at 2-weeks postintervention. Conclusions: Motivational and behavioral skills programs are effective at increasing MVPA in low-income and minority adolescents during program hours, but further research is needed to address home barriers to youth MVPA.
