Prediction of dietary adherence in cholesterol reduction: Relative contribution of personality variables and health attitudes

Abstract

The purpose of this study was to identify personality and health attitude variables that might predict adherence to a cholesterol-reducing diet.

After taking a battery of psychological inventories, 66 subjects entered a 26 week diet program. Adherence indices included attendance rate at scheduled appointments, changes in diet, and changes in serum cholesterol levels.

Of the 55 subjects with complete data, 7 dropped out, 7 attended inconsistently, and 41 completed the program. Drop-outs scored significantly lower on the Health Belief measures of seriousness, susceptibility, and benefits. Improvement in serum cholesterol was positively correlated with the Health Belief Benefits Scale and negatively correlated with the Health Locus of Control chance scale. Dietary reduction in saturated fat was positively associated with the Health Belief Seriousness and Benefits Scales.

Health attitudes and beliefs were better predictors of adherence than personality trait measures.     

Type a personality: Correlations with personality variables and nonverbal emotional expressions during interpersonal competition

Facial and other nonverbal behaviors of 52 male and female participants in an interpersonal anagrams competition were correlated with a variety of self-report personality measures. Facial expressions suggestive of negative affect were significantly positively correlated with the Framingham Type A scale and the Job Involvement and Hard-Driving subscales of the Jenkins Activity Survey. A composite nonverbal index correlated significantly with Framingham Type A, Jenkins Job Involvement and the Extraversion scale of the Eysenck Personality Questionnaire. The pattern of correlations between the nonverbal and personality measures supported the view that Type A individuals are characterized by both self-reports of and facial expression of more anger/hostility than are Type B individuals.     

Birth order and selected work-related personality variables

A possible link between birth order and various individual characteristics (e. g., intelligence, potential eminence, need for achievement, sociability) has been suggested by personality theorists such as Adler for over a century. The present study examines whether birth order is associated with selected personality variables that may be related to various work outcomes. 3 of 7 hypotheses were supported and the effect sizes for these were small. Firstborns scored significantly higher than later borns on measures of dominance, good impression, and achievement via conformity. No differences between firstborns and later borns were found in managerial potential, work orientation, achievement via independence, and sociability. The study's sample consisted of 835 public, government, and industrial accountants responding to a national US survey of accounting professionals. The nature of the sample may have been partially responsible for the results obtained. Its homogeneity may have caused any birth order effects to wash out. It can be argued that successful membership in the accountancy profession requires internalization of a set of prescribed rules and standards. It may be that accountants as a group are locked in to a behavioral framework. Any differentiation would result from spurious interpersonal differences, not from predictable birth-order related characteristics. A final interpretation is that birth order effects are nonexistent or statistical artifacts. Given the present data and particularistic sample, however, the authors have insufficient information from which to draw such a conclusion.     

Desire for control and communication-related personality variables

In a sample of 95 university students, scores on a measure of desire for control correlated .37 with willingness to communicate, supporting the notion of control as a motive for communication and also correlated .43 with self-perceived communication competence but not with communication apprehension.     

Developing an integrative social-cognitive strategy for personality assessment at the level of the individual: An illustration with regular cigarette smokers

Basic advances in social cognition have not fully translated into similar advances for personality assessment. In this study, we evaluated whether an integrated social cognitive approach to personality assessment (i.e., one that employs an idiographic assessment of a multi-faceted self-system, priming procedures, and reaction time tasks) could be applied to assess a social cognitive personality system at the individual level in a particularly challenging population: cigarette smokers. This integrative approach was necessary to detect the idiosyncratic content and contextualized structure of the three self-schemas (smoker self-schema, abstainer ideal possible self, abstainer ought possible self) that composed this social cognitive personality system. Priming different self-structures enhanced reaction times to contextually bound self-referent information. Results are discussed in terms of their implications for social cognitive theories of personality and personality assessment.     

Birth order, family structure and personality variables

The birth order and family structure variables assessed included first or only child, position in multi-child family, position in dyadic family, age of parents at birth of given child, whether reared by one or both parents, whether reared under permissive or authoritarian family atmosphere. The personality variables assessed included Sociability, Anxiety, Dominance, Superego, Phlegmatic Temperament, Involvement, Self-Regard and other scales measured by the Howarth Personality Questionnaire. One hundred seventy female and 142 male undergraduates were tested. Significant relationships found included: anxiety lower in firstborns; superego higher in firstborns; persistence higher in those not dominated by elder sibling; phlegmatic temperament higher in permissive families; involvement and phlegmatic temperament lower in single parent families; self-pride higher in the elder of a sibling pair; individual tolerance higher in children reared by both rather than single parent.     

Gender differences in alcohol dependence: personality variables, psychopathological profile and personality disorders

In this paper, gender differences in personality, psychopathology and personality disorders of alcohol-dependent patients are described. The sample consisted of 158 alcohol-dependent patients attending a psychiatric outpatient clinic (105 men and 55 women). All participants were assessed with various assessment tools related to personality (Impulsiveness Scale, Sensation Seeking Scale and STAI), psychopathology (SCL-90-R, BDI and Inadaptation Scale) and personality disorders (IPDE). There were no differences in personality variables, but the women had more anxiety and depressive symptoms and also more problems to adapt to everyday life than did the men. Personality disorders were not as prevalent as in the case of men, and the most frequent among women were obsessive-compulsive, dependent and histrionic personality disorders. Implications of this study for further research are commented on.     

Goal-setting attributes,personality variables,and job satisfaction

The relationships between four goal-setting attributes identified by factor analytic procedures and job satisfaction were investigated among 271 scientists and engineers at a nuclear research and development center. Positive relationships between the goal-setting attributes and satisfaction were found. Further, it was found that need for achievement, need for autonomy, and need for affiliation as measured by the Gough Adjective Checklist did not significantly moderate the goal-setting attribute-job satisfaction relationships.
