Changes in risk perceptions in relation to self-reported colorectal cancer screening among first-degree relatives of colorectal cancer cases enrolled in a randomized trial.

Objective: This secondary data analysis was conducted to evaluate the applicability of the Risk Reappraisal Hypothesis, which has been proposed to explain the influence of performing a health behavior on perceived risk. Data were collected in the context of a randomized trial, which found that an individually tailored, multicomponent intervention was successful in increasing colorectal cancer (CRC) screening among first-degree relatives of CRC cases. Method: The ethnically diverse study sample (N = 841; 29% Latino, 21% African American, 20% Asian) consisted of adult siblings and children (40–80 years) of CRC cases, identified through the California Cancer Registry. Data were collected at baseline and at 6- and 12-month follow-up. Changes in self-reported risk perception (perceived likelihood of developing CRC) were examined over the study period in relation to study condition and screening status. Results: Greater increases in perceived risk were observed among intervention versus control-group participants over the study period, but increases were limited to intervention participants who had not been screened. We also examined trajectories of perceived risk in relation to timing of screening receipt (e.g., before 6 months, 6–12 months, never). Continued upward shifts in risk were observed during the study period among intervention participants not screened during the study. In contrast, participants screened by 6 months displayed a reduction or leveling off in perceived risk between 6- and 12-month follow-up. Conclusion: Results provide support for the applicability of the Risk Reappraisal Hypothesis within a high-risk sample enrolled in a CRC screening promotion trial. Future research is needed to explore the impact of short-term risk reductions on future CRC screening behavior. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Understanding the multidimensionality of acculturation among Chinese Canadians.

This study evaluated a multidomain bidimensional model of acculturation among Chinese Canadians. A total of 234 university students completed measures assessing internal and external domains of Chinese and Canadian dimensions of acculturation. The results of factor analyses showed that the Chinese dimension of acculturation included internal and external domains as expected, but that the Canadian dimension included only one domain. The emergence of a third factor reflected individuals' evaluation of their cultural group as distinct from their identification with that group. The different domains of acculturation showed varying relations with participants' extent of contact with Chinese and Canadian cultures and with chronological age. Implications of these findings for research methodology and for understanding Chinese Canadians are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relationships among health perceptions vary depending on stage of readiness for colorectal cancer screening.

Objective: We explored whether relationships among health perceptions differ depending on individuals' stage of readiness for colorectal cancer screening (CRCS). Methods: Data from the National Cancer Institute's Health Information National Trends Survey (HINTS) were used to stage adults over 50 years of age (N = 2324) using a modified version of the Precaution Adoption Process Model (PAPM) staging algorithm. Health perceptions examined included perceived risk of cancer, worry about cancer, fatalism, and beliefs about ambiguity of cancer prevention recommendations. Results: Meaningful differences in patterns of relationships among health perceptions by stage were found. Conclusions: The nonlinear patterns that emerged indicate support for the role of these health perceptions in screening, the idea that behavioral readiness may moderate the relationship between important health perceptions, and the use of the stage construct in this context.

Authoritarianism and men's reactions to sexuality and affection in women.

Previous research that the authoritarian personality showed exaggerated concern with sexuality and was not able to integrate attitudes of sexuality and affection. The present research assumed that the authoritarian personality was characterized by rigidity and projection. Reactions to 2 film strips depicting the same woman in 2 different roles: as a sexy woman and as an affectionate person, were correlated with F scale scores. The hypotheses were confirmed.

Correlates of colorectal cancer screening compliance and stage of adoption among siblings of individuals with early onset colorectal cancer.

Concepts from the health belief, transtheoretical, and dual process models were used to examine how siblings of individuals diagnosed with colorectal cancer (CRC) before age 56 made decisions about CRC screening. Siblings (N=504) were assessed for CRC screening practices and intentions, pros, cons, processes-of-change, perceived risk of CRC, perceived severity of CRC, preventability of CRC, cancer-related distress, and sibling relationship closeness. Physician and family recommendation and knowledge were also assessed. Fifty-seven percent of participants (n=287) were compliant with CRC screening. Logistic regression indicated that perceived pros and cons, perceived risk, commitment to screening, health care avoidance, and sibling closeness were associated with screening compliance. Physician and family recommendation were also strong correlates. A similar set of factors was associated with stage of adoption of CRC screening.

Do personalised letters in Vietnamese increase cervical cancer screening among Vietnamese women?

In Australia, Vietnamese women are at greater risk of cervical cancer than other Australian women. To increase their participation in cervical screening, the Vietnamese community was exposed to a media campaign about the advantages of cervical smear screening which was delivered in Vietnamese through Vietnamese newspapers and radio. In addition, 689 Vietnamese (18-67 years) were selected from the electoral roll. They were randomly assigned to either receive a personal letter written in Vietnamese promoting cervical screening, or not. We report on the effect of the letter on smear rates. Being randomised to be sent such a letter was not associated with any increase in screening (relative rate of appropriate screening in the intervention versus the control group was 0.85, 95% CI 0.55-1.3). It is important to carefully evaluate untested health promotion interventions.     

Deconstructing the monolith: Differences in attitudes about mammography among low-income African American women.

The purpose of this study was to explore how health beliefs may vary within a minority group. In this mixed-method study, 63 low-income African American women engaged in six focus groups discussing beliefs that inhibited or facilitated mammography. Differences in cognitive complexity, self-efficacy, and attributions of causality occurred across neighborhoods despite the geographic proximity and demographic similarity. The attitude change that occurred during the discussion suggested ways to construct effective health interventions. The data suggest (a) that women were similarly knowledgeable about mammography and cancer, (b) knowledge did not correspond with attitudes, (c) attitudes must be addressed before knowledge can be utilized, (d) attitudes are developed and maintained within neighborhood social networks and that stories maintain these attitudes, (e) increasing the discussion among peers should lead to greater attitude change and discussion leads to increased thought, and (f) motivation and follow through are connected to women’s roles within their communities.

Psychological impact of colorectal cancer screening.

This article examines the psychological impact of participating in sigmoidoscopy screening for colorectal cancer prevention. The 1st study examined psychological well-being at 3 months, in relation to screening outcome, in 4,153 individuals. The 2nd study used longitudinal data to examine changes in psychological functioning from before to after screening in relation both to screening outcome and baseline indicators of vulnerability. There were few psychological differences between those who had received negative results or had polyps detected. These findings were confirmed in the longitudinal study, which also found no evidence for vulnerability to adverse effects among those who were initially most anxious or who perceived their risk of cancer to be higher. The longitudinal data suggested that screening might produce transient positive effects. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Comparing two theories of health behavior: A prospective study of noncompletion of treatment following cervical cancer screening.

Some women receiving abnormal cervical screening tests do not complete recommended treatment. A prospective study (N = 660) investigated the value of conceptualizing attendance at colposcopy for treatment as either (a) an active problem-solving response to a health threat, motivated by attitudes toward an abnormal result, as implied by self-regulation theory (H. Leventhal, D. Meyer, & D. Nerenz, 1980); or (b) as a behavior motivated by attitudes toward clinic attendance, as implied by the theory of planned behavior (TPB; I. Ajzen, 1985). Responses to questionnaires containing variables specified by these models were used to predict women's subsequent attendance or nonattendance for treatment over the following 15 months. Although the TPB offered superior prediction of intentions and completion of treatment, discriminant function analyses showed that consideration of both models was important in distinguishing between those who attended all their appointments as scheduled, attended after being prompted, or ceased attending. Implications for measurement and theory in health protection are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Spiritual health locus of control and breast cancer beliefs among urban African American women.

The present study examined the relationship between spiritual health locus of control, breast cancer beliefs, and mammography utilization among a sample of 1,227 African American women from urban public health centers. Spiritual health locus of control was conceptualized as having an active and passive dimension, empowering individuals in their health beliefs and behaviors or rendering them to rely on a higher power (e.g., God) to determine their health outcomes, respectively. The active dimension was negatively associated with perceived benefits of mammography and positively associated with perceived barriers to mammography. The active and passive spiritual dimensions are distinct from internal and external health locus of control. Further study of their associations with other health-related beliefs and behaviors is warranted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Acculturation and adjustment among immigrant Chinese parents: Mediating role of parenting efficacy.

This study examined parenting efficacy beliefs as a mediator of the association between acculturation and adjustment. The sample consisted of 177 immigrant Chinese mothers and fathers with early adolescent children in Canada. Acculturation was assessed bidimensionally as Canadian and Chinese orientations. A latent psychological adjustment variable was composed of symptoms of depression, feelings of self-esteem, and life satisfaction. Results showed that relations between Canadian orientation and psychological adjustment were partially mediated by parenting efficacy. As expected, the more parents were oriented toward Canadian culture, the more efficacious they felt in their parenting, which in turn was associated with better psychological adjustment. In contrast, mediation of relations between Chinese orientation and psychological adjustment was not supported, as Chinese orientation was not associated with parenting efficacy and was positively associated with psychological adjustment for mothers only. Similar results were found when the meditational model was extended to evaluate parenting practices as an outcome (i.e., warmth, reasoning, and monitoring). That is, parenting efficacy mediated the relation between higher Canadian orientation and more positive parenting practices, whereas Chinese orientation was unrelated to parenting practices. Invariance testing suggested that the models were similar for mothers and fathers. Results support the theory that higher orientation to Canadian culture may advance feelings of parenting efficacy because parents have the cultural knowledge and skills to feel confident parenting in a new intercultural context. Further, they support the expectation that parenting efficacy beliefs, in turn, are important determinants of psychological adjustment and effective parenting for immigrant parents.

Sexuality and life skills education: A multistrategy intervention in Mexico.

This contribution presents a set of intervention programs in the area of reproductive health, sexuality, and life-skills education that are now widely used in Mexico and with Latin American populations elsewhere. First, the authors briefly indicate how a research-informed approach has been central to the development and implementation of these interventions. Thereafter they describe how the programs were initially designed, taking into consideration the Mexican cultural context and its implications for Mexican adolescents. They also mention subsequent evaluation-based extensions of the programs to reach other target populations, to broaden the range of issues addressed, to promote their dissemination, and to advocate society-wide sexuality and life-skills education.

Mental health screening: Utility of the Psychological Screening Inventory.

The Psychological Screening Inventory (PSI) was designed for use as a rapid mental health screening device to identify persons who should receive more extensive evaluation. This study evaluated the accuracy of the three screening scales using receiver operating characteristic (ROC), positive predictive power-negative predictive power, and sensitivity-specificity analyses. Persons with major psychiatric disorder (N = 536) were distinguished from control participants by the Alienation scale with an area underneath the ROC curve (AUC) of .905; persons with significant antisocial behavior (N = 410), by the Social Nonconformity (Sn) scale with an AUC of .811; and persons with general psychological distress (N = 620), by the Discomfort (Di) scale with an AUC of .773. There were comparable findings for the other comparison procedures, and some results were better for men and women separately. An empirically developed index (the Overall Screening Index--Revised) showed significant improvement over the Di scale in identifying persons with general psychological distress (AUC = .842). These findings support the utility of the PSI for its intended purpose. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Status of sexuality in contemporary psychoanalytic psychotherapy as reported by therapists.

Contemporary psychoanalytic literature places less emphasis than its classical counterpart on sexuality in explaining human motivation. However, up until now no methodical research has been done on the status of sexuality in clinical work. We report on a qualitative interview study that examined the status of sexuality in psychoanalytically oriented psychotherapy (n = 10). We studied the extent to which therapists used sexual factors to explain patient behavior: To what extent were sexual themes dominant in the treatment, what importance did therapists attach to them, and what factors affected their place in therapy? The data gathered from the investigation were related to theoretical thinking on the marginalization of sexuality in psychoanalytic theory and practice. On the basis of the investigation, we describe four factors that affect the status of sexual themes in therapy: the extent of the belief in the centrality of sexuality in human motivation, the level of expressiveness of therapy, the narrowing of the concept of sexuality and the separation between sexuality and intimacy, and the tendency to avoid sexual issues because of the discomfort their discussion causes to patient or therapist.

The effects of message framing and ethnic targeting on mammography use among low-income women.

The authors examined the effects that differently framed and targeted health messages have on persuading low-income women to obtain screening mammograms. The authors recruited 752 women over 40 years of age from community health clinics and public housing developments and assigned the women randomly to view videos that were either gain or loss framed and either targeted specifically to their ethnic groups or multicultural. Loss-framed, multicultural messages were most persuasive. The advantage of loss-framed, multicultural messages was especially apparent for Anglo women and Latinas but not for African American women. These effects were stronger after 6 months than after 12 months. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

紫花牡荆素体外抑制人宫颈癌HeLa细胞增殖的研究

Objective: The aim of the study was to investigate the effect of Casticin on proliferation inhibition of human cervical cancer HeLa cells in vitro and to unravel the associated mechanisms. Methods: Human cervical HeLa cells were cultured in vitro. The inhibitory effect of Casticin on the viability of human cervical cancer HeLa cells was evaluated by the MTT assay.The colony formation ability was detected by plate colony formation assay. Distribution of cell cycle was analyzed by flow cytometry. The protein expression levels were analyzed by Western blot. Results: Casticin significantly inhibited the growth of human cervical cancer HeLa cells in a dose- and time-dependent manner, and the IC50 was 2.82 μg/mL. The colony-forming rate was reduced drastically compared with control group (P ＜ 0.05). The cells were markedly arrested at G2/M phase after the treatment of Casticin for 48 h. Western blot showed that the expression of p21 protein was up-regulated and protein level of Cyclin B1 was depressed by Casticin in a concentration dependent manner. Conclusion: Casticin could inhibit the cell growth and lead to cell arrest in human cervical cancer HeLa cells, and the down-regulation of Cyclin B1 protein expression and activation of p21 protein might contribute to Casticin induced cell arrest in human cervical cancer HeLa cells.
