Personality adjustment and the study of abnormal psychology.

Rorschach story-completion test and autobiographical data were obtained from 21 students in an abnormal psychology class and 22 students in a history class, both at the beginning and the end of the semester. Comparisons of the pre- and post-test data "support the belief that, (a) as a group, students studying abnormal psychology differ in personality from those not enrolled in the course, and (b) while the study of abnormal psychology has little immediate effect on personality ad ustment, measurable changes occur which appear to be related to course experience."

Outcomes measurement in today''s health care environment

The effects of smoking habits on thyroid function, echo-texture (nodules and/or cysts) and thyroid gland volume were determined by using ultrasound and measuring serum Thyroxin (T4), Triiodothyronine (T3), Thyrotropin (TSH) and TPO antibodies (ab-TPO) in 189 healthy smokers and non-smokers, randomly selected (111 females and 78 males) among the employees of our hospital and their relatives. When the entire group of subjects was considered the mean ratio of thyroid gland volume/body weight was found to be significantly higher in male (P < 0.05) and female (P < 0.05) smokers compared with non-smokers. In female smokers, mean serum thyroid-stimulating hormone (TSH) was lower (P < 0.05) and the degree of smoking was positively correlated with the ratio of thyroid gland volume/body weight (P < 0.05). However, when the subjects with a family history of goitre in first degree relatives were excluded from our study (14 females and 9 males), no significant differences in mean ratio of thyroid volume/weight or TSH between the remaining smokers and non-smokers were detected. In both sexes, the correlation between the degree of smoking and thyroid volume, although positive, did not reach statistical significance. No difference in prevalence of abnormal echogenicity and echo-texture (nodules and cysts) between smokers and non-smokers was detected. It is concluded that smoking habits present a goitrogenic effect only in subjects with a family history of goitre but have no influence on thyroid gland texture.     

Proximal versus distal cues to smoke: The effects of environments on smokers' cue-reactivity.

Smokers are highly reactive to smoking-related cues that are directly linked, or most proximal, to actual smoking behavior (e.g., lit cigarettes). However, over the course of smoking, proximal cues may not be the only stimuli to become strongly associated with smoking. Distal cues, such as the environments in which smoking occurs (e.g., bar) might also gain associative properties and come to evoke robust reactivity from smokers. To test this, a pilot study was first conducted to develop standard pictorial stimuli of smoking and nonsmoking environments, all of which were completely devoid of proximal smoking cues. A comparison set of smoking and nonsmoking proximal cues was then created. Using the 12 total pictorial cues developed, 62 adult smokers participated in a cue-reactivity study during which they viewed and rated pictorial smoking and nonsmoking environment and proximal cues. Results demonstrate that, similar to proximal cues, environments associated with smoking can alone function as stimuli capable of evoking strong subjective reactivity from smokers. This work supports a broader conceptualization of drug-related cues in cue-based research and treatment development that includes proximal and distal cues as distinct categories.

The deaf child's conception of physical causality.

In an attempt to assess their causal thinking relative to hearing children of normal emotional status and emotionally disturbed hearing children, the responses of 12 deaf children, aged 8-10 yr., to question dealing with physical causality were compared with those of groups of emotionally disturbed and undisturbed hearing children of similar age and intelligence. Questions asked were of 2 experience levels, depending upon the accessibility of the causal agent to direct experience. Each child was asked 8 questions at each level. It was found that: (a) Significant differences among groups appeared with items whose causal agents were not accessible to direct experience, (b) The "prelogical" responses of the deaf tend to be of a phenomenistic nature. Those of the emotionally disturbed and normals are more inclined toward the animistic and dynamic categories. (c) By the age of 12 yr. no measurable group differences appeared. (17 ref.)

The short-term effect of a smoking prevention program for the upper graders of elementary schools--the results of intervention study for two years with quasi-experimental design

The purpose of this study was to evaluate the short-term effect of a smoking prevention program for Japanese elementary school-children in the fifth and sixth grades. The program was developed with concepts found in the Know Your Body Program and the conclusions of a National Cancer Institute-convened Expert Advisory Panel, and focused on teaching about the short-term effects of smoking and on resistance to social pressures to smoke. The study was conducted with a quasi-experimental design. An intervention group (52 boys and 54 girls) received three sessions for both the fifth grade in 1992 and the sixth grade in 1993. Moreover, the intervention group received a pre-test before the first session and a post-test after the third session in each grade. A comparison group (102 boys and 91 girls) received the same tests at the same time as the intervention group, but did not receive any program on smoking prevention. The short-term effect of the program were evaluated using the results of the pre-test in the fifth grade and of the post-test in the sixth grade in both groups. The results were as follows: 1) Remarkable short-term effects of the intervention were seen in respect to awareness of the importance of not smoking in girls, and also in the knowledge of the short-term effects of smoking in both sexes. 2) The intervention was not effective with respect to intention to smoke at the age of 20 and self-efficacy of refusing to smoke in both sexes. 3) The short-term effects were not clear in the smoking behavior in both sexes because the rates of ever smokers and of monthly smokers were almost the same for two years between the intervention group and the comparison group. 4) The smoking behaviors of children, their parents and their best friends had little influence on the results of the post-test in the sixth grade.     

A reply to Kaplan and Parlow: Minority rights and public health are not mutually exclusive.

It is unfortunate that Kaplan and Parlow (1988) misinterpreted our plea for justice and compassion in balancing the rights of smokers and non-smokers (1987; see record 1989-01264-001) as a blanket endorsement of smokers' rights to expose abstainers to environmental tobacco smoke (ETS). We absolutely do not advocate such a straw man; obviously, innocent third parties have the right to be protected. Kaplan and Parlow's assertion that our position is that "smoking is not a legitimate threat" is totally incorrect. In pointing to the controversy in the scientific literature about the degree of risk associated with ETS, we were not arguing that the risk is non-existent, nor that smokers are entitled to do as they please if others are adversely affected (or even if abstainers simply find ETS esthetically objectionable). Rather, we were emphasizing that the warlike rhetoric, emotionalism, and morally superior stance of the anti-smoking crusade can have a negative impact on the scientific objectivity that ought to guide social policy. The commendability of one's goals is not an excuse for ignoring contrary evidence or failing to examine the evidence for preferred hypotheses as critically as one would the support for unpopular causes. Our concern in our article, which Kaplan and Parlow failed to realize, was with how the rights of both smokers and non-smokers can best be achieved with a minimum of social and personal costs. The intent of our article was to remind readers that, in the past, emotionality and haste on the part of well-intentioned reformers have often been responsible for unnecessary social disruption and trammelling of individual rights--all while failing to achieve their noble goals. We agree with Kaplan and Parlow's position that individuals must be protected from exposure to unwanted ETS and that is the position we took in our article. This, however, can be done without creating greater social problems by trampling on the rights of smokers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Regret and rationalization among smokers in Thailand and Malaysia: Findings from the International Tobacco Control Southeast Asia Survey.

Objective: To test whether differences of history and strength in tobacco control policies will influence social norms, which, in turn, will influence quit intentions, by influencing smokers’ regret and rationalization. Design: The data were from the International Tobacco Control (ITC) Policy Evaluation Southeast Asia Survey, a cohort survey of representative samples of adult smokers in Thailand (N = 2,000) and Malaysia (N = 2,006). The survey used a stratified multistage sampling design. Main Outcome Measures: Measures included regret, rationalization, social norms, and quit intention. Results: Thai smokers were more likely to have quit intentions than Malaysian smokers. This difference in quit intentions was, in part, explained by the country differences in social norms, regret, and rationalization. Reflecting Thailand’s history of stronger tobacco control policies, Thai smokers, compared with Malaysian smokers, perceived more negative social norms toward smoking, were more likely to regret, and less likely to rationalize smoking. Mediational analyses revealed that these differences in social norms, accounted, in part, for the country-quit intention relation and that regret and rationalization accounted, in part, for the social norm-quit intention relation. Conclusion: The results suggest that social norms toward smoking, which are shaped by tobacco control policies, and smokers’ regret and rationalization influence quit intentions.

The effects of smoking and smoking abstinence on verbal and visuospatial working memory capacity.

Several studies have examined the effects of smoking and abstaining from smoking on working memory (WM) but have yielded inconclusive findings. Thus, the authors used a repeated measures design to assess the effects of smoking and abstaining from smoking on both visuospatial and verbal WM capacity (WMC) using highly reliable, well-validated, and theoretically driven WM span tasks. Verbal n-back was also administered to examine its relationship to these complex WM span tasks and to compare this study's results with previous findings. Smokers (n = 23) and nonsmokers (n = 21) participated in 2 sessions separated by 1 week. During 1 session, smokers completed the WM tasks after abstaining from smoking for at least 12 hr, whereas in the other session smokers did not abstain from smoking and were tested immediately after smoking (all WM tasks were completed 45 min or less since last cigarette). Results indicated that smokers' verbal WM span was lower than nonsmokers' and was lower during the nonabstinent session compared with the abstinent session. Smokers' verbal n-back performance was also lower than nonsmokers', although there was no difference in verbal n-back performance between the smoking sessions. In contrast, there was no difference in visuospatial WM span between the smoking sessions or between smokers and nonsmokers. Taken together, these findings demonstrate that (a) smokers' verbal WM is lower than nonsmokers, (b) smokers' verbal WMC is lower during nonabstinence compared with abstinence, and (c) smoking exhibits differential effects on the different WM domains.

Immediate Antecedents of Cigarette Smoking in Smokers With and Without Posttraumatic Stress Disorder: A Preliminary Study.

Using ambulatory methods for 1 day of monitoring, the authors of this study investigated the association between smoking and situational cues in 63 smokers with posttraumatic stress disorder (PTSD) and 32 smokers without PTSD. Generalized estimating equations contrasted 682 smoking and 444 nonsmoking situations by group status. Smoking was strongly related to craving, positive and negative affect, PTSD symptoms, restlessness, and several situational variables among PTSD smokers. For non-PTSD smokers, the only significant antecedent variables for smoking were craving, drinking coffee, being alone, not being with family, not working, and being around others who were smoking. These results are consistent with previous ambulatory findings regarding mood in smokers but also underscore that, in certain populations, mood and symptom variables may be significantly associated with ad lib smoking.

Experimental effects of ego-defense preference on interpersonal relations.

The hypothesis that a connection exists between the personality personality defenses of interacting individuals and their attitudes toward and perceptions of their interaction is explored by assessing the defense mechanisms of a group of Ss to psychosexual stimuli, the Blacky Pictures, and evaluating their interaction when pairs of Ss are engaged in a task which arouses a specific psychosexual disturbance. The results indicate that the interaction of two people who project the same psychosexual impulse is more negative than pairs of people who use other defenses. Dissimilar defenses do not seem to adversely affect the interaction; however, when both partners have high conflict, more negative interaction tends to result than when only one is disturbed. The relative hierarchies of defense mechanisms and psychosexual dimensions, with regard to their effect on interpersonal relations are discussed.

Punitiveness, authoritarianism, and parental discipline of grade school children.

"The purpose of this study was to investigate the interrelationships among ethnocentrism-authoritarianism in children, the child's willingness to be punitive, and the punitiveness of the parent as the child sees it. Three hypotheses postulating positive correlations among the three variables were set up… . It is concluded that the three hypotheses of the study are supported by the data, and that this evidence is in accord with, and reflects favorably upon, the theory of the origin of ethnocentrism-authoritarianism proposed by Frenkel-Brunswik and her associates."

Menopausal age in relation to smoking

A population study of women revealed more smokers among 50-year-old postmenopausal women than among women of the same age who still menstruated. The difference was statistically significant. The postmenopausal smokers had on average smoked as long as or longer than the smokers who still menstruated. The higher number of smokers among postmenopausal women could thus not be explained by these women starting to smoke in connection with the menopause. Non-smoking women were on average heavier than smoking women. Previous studies indicate that an increased amount of adipose tissue might delay the menopausal age. It is therefore possible that the difference in menopausal age between smoking and non-smoking women might be explained either by a delayed menopause in non-smoking women due to an increased amount of adipose tissue in these women, or by a precocious menopause in smokers due to toxic effects from smoking. Probably both factors are of importance, but our results indicate that smoking per se is the main factor. The increased number of smokers among women with precocious menopause can probably explain part of the overrepresentation of women with precocious menopause among those who have myocardial infarction.     

Characterization of the tyrosine phosphorylation and distribution of dystrobrevin isoforms

While level of school education has been related to prevalence of cigarette smoking in a number of studies, less information is available on the role of vocational education and related occupational contexts. This study analyses the relative contribution of different types of educational experience to explaining prevalence and intensity of cigarette smoking in a large sample of female and male vocational trainees in Germany. A standardized questionnaire on smoking behaviour and educational performance was applied in 27 educational centers across the country, covering a total of 20,527 respondents (77.3% of the original sample; women: 59.5%, men: 40.5%). Bivariate analysis revealed a high prevalence of current smokers among vocational trainees, both men (51.2%) and women (49.4%). Men were more likely to be heavy smokers, especially with increasing age. In both sexes, prevalence of smoking was particularly high in the following occupational groups: hairdressers, butchers, painters, service personnel (hotels, restaurants), shop assistants/sellers and cooks. Multivariate analysis taking educational level, type of vocational training (occupation), age, sex and urban-rural background into account revealed the highest prevalence odds ratios (POR) of smoking in subjects with the lowest educational level (POR = 5.19 for men and 4.56 for women). Even stronger effects were observed with smoking intensity (> or = 20 cigarettes/day): in men with the lowest educational level the risk of being a heavy smoker was 8.92, and in women 13.54 compared to subjects with a high-school leaving qualification. Poor school education must be considered the relatively strongest predictor of prevalence and intensity of cigarette smoking in a large sample of female and male vocational trainees. Preventive efforts should be directed at specific target groups such as those identified by this study.     

Prison health: a matter of priority

Carboxyhaemoglobin (COHb) concentrations were determined by differential spectrophotometry in blood of 60 healthy adult subjects from various locations in Lagos. Half of these were either occasional or regular tobacco cigarette smokers. Our findings showed that the Lagos dweller has elevated COHb concentration ranging between 7.6%-9.9%, several folds higher than permitted by Air Quality Standards. The range and scatter of COHb in smokers were wider (7.4%-13.0%) than in non smokers. In particular, COHb concentrations were significantly higher in regular smokers than in non smokers by Fisher's exact test (p < 0.0006). Elevated COHb concentrations among smokers were related to frequency of tobacco use (p < 0.01). There was however no statistically significant difference in COHb concentrations when the regular and occasional smokers were taken as a group and compared with the non smokers. Haematocrit measurements showed that a degree of anaemia was present in most of the subjects tested irrespective of smoking status (mean packed cell volume = 36.1). It is inferred from this data that the Lagos dweller has high ambient concentrations of COHb and that these may be further aggravated by cigarette smoking.     

Morphology and ultrastructure of the antennal chemoreceptors and mechanoreceptors of worker Coptotermes formosanus Shiraki

Data on respiratory symptoms and smoking for 2749 white American high school students from two linked surveys, separated by a one year lapse, are presented. There was a significantly higher likelihood of smoking at second survey among those who had initial symptoms. (There had been no educational efforts linking smoking and respiratory symptoms in the interim.) This difference was almost entirely contributed by those who had been ex-smokers and light (less than or equal to four cigarettes/day) smokers at first survey. Initial ex-smokers and light smokers also had, overall, least fixed smoking habits. Whatever the initial smoking or symptom status, symptoms at second survey were far more likely with current smoking. Controlling for initial symptom and smoking status, the gradient of symptoms between current smokers and non-smokers was over two and a half fold, except among those who had had symptoms and had not been smoking, and whose initial symptoms presumably arose from causes other than current cigarette smoking. Even among that group, symptoms at second survey were half as likely again among those who reported having become smokers (p less than-001). There were also strong linear trends of increased likelihood of symptoms with increased numbers of cigarettes smoked. Symptom rates at second survey of those who had symptoms a year earlier, and who stopped smoking during the year, were not as low as for those who also stopped smoking, but who had not had initial symptoms, suggesting that symptoms associated with smoking were not completely reversible in the time interval of this study. The difference, however, was not significant.     

The effects of smoking on bone mass and the rates of bone loss among elderly Japanese-American men

Bone density and bone loss rates were examined among Japanese-American men categorized as current cigarette smokers, past smokers, and nonsmokers. The design included a retrospective study of smoking and bone density and a prospective study of current smoking and bone loss rates. The mean length of follow-up was 5 years; the setting was the island of Oahu. The subjects included 1303 men in the Hawaii Osteoporosis Study, 51-82 years old at their initial examination. Twenty percent were current smokers, 45% past smokers, and 35% had never smoked. Their bone density was measured at the distal and proximal radius and calcaneus using single photon absorptiometry. Compared with never smokers, current and past smokers had significantly lower bone density, especially in the predominantly cancellous calcaneus (4.8 and 4.3% lower, respectively) and partially trabecular distal radius (1.8 and 3.3% lower, respectively). The magnitude of the smoking effect was linked strongly to the duration of smoking and also to the number of cigarettes smoked. Bone loss rates subsequent to the initial measurement were greater in the current smokers than the never smokers (20.5, 27.2, and 9.7% greater at the calcaneus, distal, and proximal radius, respectively) but the differences did not achieve significance. Smokers of more than one pack per day had 32.0, 77.6, and 30.7% greater loss rates than never smokers in these same sites; the difference achieved significance at the distal radius. The results from the distal radius suggest that these smokers may increase their fracture risk 10-30% per decade of smoking. The adverse effects of smoking appeared to be greater in cancellous than cortical bone.     

Why do lower educated people continue smoking? Explanations from the longitudinal GLOBE study.

This article describes the effect of educational level on the decision to continue smoking among 1,354 initially smoking participants (age≥20 years) in the Dutch GLOBE study. The effect of education continued smoking was explained from baseline information (1991) on smoking characteristics, individual characteristics, and environmental factors. Smoking status was reassessed after 6.5 years. Lower educated smokers more often continued smoking (odds ratio 2.09). Poor perceived health and earlier smoking initiation in lower educated groups were main predictors of educational differences in smoking maintenance. Educational differences in chronic illness, perceived control, neuroticism, and emotional support also contributed to the explanation of educational differences in continued smoking. These results have important implications for intervention programs and policy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Autonomy Over Smoking Scale.

Our goal was to create an instrument that can be used to study how smokers lose autonomy over smoking and regain it after quitting. The Autonomy Over Smoking Scale was produced through a process involving item generation, focus-group evaluation, testing in adults to winnow items, field testing with adults and adolescents, and head-to-head comparisons with other measures. The final 12-item scale shows excellent reliability (αs = .91–.97), with a one-factor solution explaining 59% of the variance in adults and 61%–74% of the variance in adolescents. Concurrent validity was supported by associations with age of smoking initiation, lifetime use, smoking frequency, daily cigarette consumption, history of failed cessation, Hooked on Nicotine Checklist scores, and Diagnostic and Statistical Manual of Mental Disorder (4th ed., text rev.; American Psychiatric Association, 2000) nicotine dependence criteria. Potentially useful features of this new instrument include (a) it assesses tobacco withdrawal, cue-induced craving, and psychological dependence on cigarettes; (b) it measures symptom intensity; and (c) it asks about current symptoms only, so it could be administered to quitting smokers to track the resolution of symptoms.

Epithelial permeability, inflammation, and oxidant stress in the air spaces of smokers

The mechanism responsible for the increased air-space permeability in cigarette smokers is unknown. The aim of this study was to assess the acute and chronic effects of cigarette smoking on epithelial permeability, inflammation, and oxidant stress in the air spaces of smokers. Fourteen cigarette smokers underwent 99mTc-diethylenetriamine pentaacetic acid (99mTc-DTPA) lung scans after abstaining from smoking for 12 h (chronic smoking) and 1 h after smoking two cigarettes (acute smoking). Each smoker also underwent bronchoscopy and bronchoalveolar lavage (BAL) after either chronic (n = 8) or acute smoking (n = 7). Seven nonsmokers also underwent bronchoscopy and BAL. The time to 50% clearance of 99mTc-DTPA (t50) after chronic smoking was 16.7 +/- 1. 3 min (mean +/- SE), and was further reduced after acute smoking to 14.8 +/- 1.0 min (p < 0.01). Neutrophil numbers were increased in bronchoalveolar lavage fluid (BALF) in the acute smoking group as compared with the nonsmokers (p < 0.05). Superoxide release from mixed BAL leukocytes was increased after chronic (p < 0.01) and acute (p < 0.001) smoking, as were thiobarbituric acid-reactive species (TBARS), providing evidence of lipid peroxidation in plasma (chronic, p < 0.05; acute, p < 0.05). Trolox equivalent antioxidant capacity (TEAC) was reduced in plasma (p < 0.001) and increased in BALF (p < 0.05) in both smoking groups. The study therefore showed an acute increase in epithelial permeability and an increase in the number of neutrophils in the air spaces of cigarette smokers concomitant with evidence of increased oxidant stress.     

Daily patterns of conjoint smoking and drinking in college student smokers.

Epidemiological data indicate a robust association between smoking and alcohol use. However, a critical question that is less resolved is the extent to which the smoking event takes place during the time of alcohol consumption. The present study used data from an 8-week prospective web-based study of college student smokers to examine daily associations between smoking and alcohol use, using measures of both likelihood and level of use. Findings indicated that consumption of alcohol and smoking covaried on a daily basis per person. In addition, consistent with the idea of smoking as a social activity for college students, light smokers were more likely than heavier smokers to smoke while drinking and to smoke more cigarettes while drinking. Smoking behavior among light smokers may be influenced by external social contextual cues, in contrast to heavier smokers who may be more affected by internal cues. Implications of findings for prevention work suggest the importance of targeting social situations in which smoking and drinking co-occur. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
