Abuse, health locus of control, and perceived health among HIV-positive women.

This study of 230 predominantly poor Hispanic and African American women aged 25 to 61 years living with HIV/AIDS in New York City revealed high levels of both sexual (39%) and physical (44%) trauma before the age of 16. Both types of early trauma were correlated with later trauma, and all forms of trauma were significantly associated with current perceived health. In multivariate analyses controlling for relevant covariates, the Powerful Others and Internal Control subscales of the Multidimensional Health Locus of Control Scales (K. A. Wallston, B. S. Wallston, & R. DeVellis, 1978) acted as independent predictors of perceived health rather than (as hypothesized) mediators of the association between trauma and perceived health. Findings underscore the importance of addressing trauma and perceptions of control over one's physical health in the provision of health services to HIV-positive women.     

Control Beliefs and Faith as Stress Moderators for Korean American Versus Caucasian American Protestants

Examined relationships among negative life events, four locus of control attributions (Internality, Powerful Others, Chance, and God Control), and psychological distress for Korean American versus Caucasian American Protestants. Negative events and Powerful Others beliefs were positively related to distress, whereas Internality was negatively related to distress. Ethnicity and God Control interacted: The relationship between God Control beliefs and anxiety was negative for Caucasians but positive for Koreans. Three-way interactions (Ethnicity × Locus of Control × Negative Events) also emerged. As Caucasians' Powerful Others beliefs increased, the positive relationship between negative events and depression became stronger; Koreans' Powerful Others beliefs had no such effect. As Caucasians' God Control beliefs increased, the negative event–depression relationship changed from positive to negative; the reverse was true for Koreans. Findings support the value of assessing ethnoculture and religiousness in stressful life events research.     

Some correlates of health locus of control among multicultural individuals

The relationship of locus of control to depression, anxiety, hostility, and physical health was assessed in a sample of multicultural college students (N = 162). Powerful Others Health Locus of Control was correlated with depression, anxiety, hostility, and recent physical symptoms while Chance Health Locus of Control (CHLC) was correlated with all of the above as well as chronic physical symptoms and major health problems. When controlling for a variety of health risk factors (viz., age, sex, body mass, exercise, smoking, salt, alcohol, and caffeine), only CHLC remained significant in the physical health models. Results support the cognitive model of mental health which emphasize the importance of adaptive beliefs. Specifically, they suggest that issues about control are related to negative affect and indicate that the often-cited relationship of an external locus of control to depression and anxiety also holds for hostility. The findings do not, however, support the view that anxiety and depression are associated with different types of external locus of control but rather suggest a unified set of locus of control beliefs underlying the three types of negative affect. In addition, evidence is provided for the external validity of the Multidimensional Health Locus of Control (MHLC) Scales with respect to mental health. Further, the results indicate that belief about one’s health may play a significant role in one’s physical health and that the health behavior model of the relationship between locus of control and physical health is insufficient to explain the relationship. As the Chance and Powerful Others MHLC scales were not related to health habits in this sample but were related to mental health (viz., depression, anxiety, and hostility), locus of control beliefs may be related to physical health via their relationship with mental health.     

Psychological and physical variables as predictors of coping strategies

26 women and 17 men between the ages of 26 and 62 yr. of age and diagnosed as having chronic illnesses were administered four questionnaires to assess physical and psychological variables and coping strategies: the Sickness Impact Profile, the Time Reference Inventory, and the Multidimensional Health Locus of Control. The Jaloweic Coping Scale assessed coping strategies. Canonical correlation indicated a single-factor link (Wilks' lambda) between scores on the first 3 tests, and the subscales of the coping scale. A significant but small correlation of .31 between the Multidimensional Health Locus of Control subscale, Powerful Others, and the coping subscale of Emotion-focused strategies was observed, that with the subscale Chance and the coping subscale confrontive strategies was negative. A second canonical correlation deleting the Time Reference Inventory score of age extension and including the three Sickness Impact Profile subscales was significant and positive for the Composite score and the subscale Palliative of the Jaloweic Coping Scale. Such data suggest that individuals who have a locus of control orientation of Powerful Others respond to chronic illness with emotionally based behaviors. In addition, chronically ill individuals who are physically dysfunctional tend to respond with palliative coping strategies.     

Measuring health beliefs on the Internet: A comparison of paper and Internet administrations of the Multidimensional Health Locus of Control Scale

A growing number of studies have supported the use of unidimensional psychometric test instruments administered via the Internet; however, support for the use of multidimensional scales is weak. The present study compares paper and Internet administrations of the Multidimensional Health Locus of Control (MHLC) Scale (Wallston & Wallston, 1981). In terms of reliabilities and factor structures, the Internet data were found to be at least as good as the paper data. MHLC scores were comparable for paper and Internet administrations, although the Internet sample scored significantly lower on the Powerful Others subscale. Overall, the results show that administration of the MHLC Scale via the Internet can produce data comparable to that obtained by pen-and-paper methods. However, it is concluded that generalization of these findings beyond the psychometric test instrument and sampling procedures used here is not warranted.     

Validation of health locus of control patterns in Swedish adolescents

The purpose of the present study was to investigate the relationships between Health Locus of Control (HLOC) questionnaire subscales (Internal, Powerful Others, Chance) and self-esteem in Swedish adolescents (N = 506). Results from traditional correlational analyses were compared with findings using an alternative method of clustering individuals according to their pattern of scores on the three HLOC subscales. One-way analysis of variance, with eight possible groupings of high and/or low scores on the three subscales, indicated that those with a combination of strong belief in internal control of health, high degree of belief that health is determined by powerful others, and low degree of belief that health is a function of chance/luck had better self-esteem than those with a quite opposite pattern, involving high belief in chance and low belief in internal control. The potential benefit to researchers and clinicians of using this method of combining the HLOC subscales, instead of the traditional correlational method, is discussed.     

Validation of a new multidimensional health locus of control scale (form c) in asthma research

Abstract

This study developed and validated an Asthma Multidimensional Health Locus of Control (AMHLC) scale using 186 asthmatics aged 13 to 55 years recruited from 46 pharmacies in the Hunter Valley, Australia. The construct validity and internal consistency of the scale were demonstrated using principal components factor analysis and Cronbach's alpha respectively. Although correlations were modest, findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those with higher “Chance” scores. Powerful Others orientation was also associated with expectations and valuation of services doctors' provide. Knowledge of asthma was not related in the expected direction with the new scale, nor were clinical indices of asthma severity. Younger asthmatics had higher Chance scores while older asthmatics tended toward higher Powerful Others orientation. Overall, the AMHLC instrument achieved suitable measurement properties to allow further investigation of health care behavior in people with asthma.     

Health locus of control of joggers and nonexercisers

To gain a better understanding of why some people engage in regular leisure-time physical exercise while others remain sedentary, the Multidimensional Health Locus of Control scale was distributed to 123 younger joggers and 93 nonexercisers. Analysis of the responses indicated that the joggers scored significantly higher on the internal subscale than did the nonexercisers. No significant differences were found on the Chance and Powerful Others subscales. The disparity of these results from those of other studies of the relationship between locus of control and exercise suggest that an exercise specific locus of control scale needs to be developed. The confound of age with exercise and locus of control requires clarification.     

Predictors of proficient technique and successful lesion detection in breast self-examination

Seventy-three women attending a health fair completed a questionnaire that measured demographic and health history variables, knowledge, and current practice of breast self-examination (BSE), Multidimensional Health Locus of Control (MHLC; Wallston, Wallston, & DeVellis, 1978), and components of the Health Belief Model (HBM; Rosenstock, 1974) in relation to breast cancer and BSE. These variables formed the basis of a conceptual model of BSE behavior that was examined by having each woman participate in a behavioral trial with a breast model in which her BSE technique and ability to detect simulated tumors was assessed. Regression analyses revealed that self-confidence in the efficacy of BSE was the best single predictor of proficient BSE. Powerful others HLC, knowledge of correct BSE behaviors, and chance HLC, respectively, also contributed significantly to the variance in performance. As anticipated, successful lesion detection was most strongly associated with more proficient BSE technique and higher frequency of BSE practice in the past six months. Internal HLC scores were not predictive of either behavioral measure. Similarly, except for perceived efficacy of BSE, HBM variables showed no strong relationships to observed behavior.     

Verbally Expressed Wishes of Children and College Women Students

This research examined the relationship between locus of control and two academic-related variables: study habits and attitudes, and college academic performance. Subjects were administered (a) the Brown-Holtzman Survey of Study Habits and Attitudes and (b) the Levenson Internal, Powerful Others, and Chance scales, the latter providing separate measures of two external control dimensions. Results indicated that internal control was related positively to effective study habits and attitudes and to college academic success, while the opposite was true for powerful others and chance control. Additional findings demonstrated significant differences between powerful others and chance control as related to study habits and attitudes and to college grade-point averages.     

Secretarial and management students: Attitudes,attributes, and career choice considerations

Secretarial and management students were compared on characteristics that have differentiated between traditional and nontraditional career women. Fifty-five female secretarial students and 55 female management (bachelor of commerce) students completed the following measures: (a) the Work and Family Orientation Questionnaire (WOFO); (b) the Attitudes toward Women Scale (AWS); (c) the Powerful Others, Personal Control, and Chance Scales (I-E Scale); (d) the Personal Attributes Questionnaire (PAQ); and (e) a measure of career choice considerations. The groups differed on two aspects of the WOFO (competitiveness and desire to master difficult intellectual challenges), and on Personal Control, sex role orientation (PAQ), and career choice considerations. The results are discussed with respect to sex role socialization and the denigration of secretarial work.     

The development of a smoking-specific locus of control scale

Abstract

A 32-item questionnaire was designed to measure multidimensional locus of control beliefs specifically about giving up smoking (SLC Scale), and administered along with the Multidimensional Health Locus of Control Scale (MHLC) and a short smoking information questionnaire to 211 smokers. Psychometric analyses of the SLC scales included a series of repeated factor and reliability analyses which resulted in a final three-factor solution, containing 11 of the original SLC items. The three factors represented the following types of locus of control for smoking: a combined Internal-Chance factor, a Significant Others factor, and a Powerful Others factor with Chronbach's alpha coefficients of internal reliability of 0.63, 0.56 and 0.55 respectively. Analyses relating to the reliability and validity of the SLC scale are presented and discussed. As expected the SLC correlated more sensibly and significantly with subjects' reported behaviour and intentions regarding giving up smoking than did the MHLC scales.     

Defensive externality and its relation to academic performance.

This study examined the relationship between locus of control and academic performance by evaluating the academic achievement of defensive externals, which has been considered a confounding factor in previous research. A further objective was an examination of the effect of two mediating variables in their relation to locus of control and academic performance. One hundred sixty college students were administered the Internal, Powerful Others, and Chance scales, the Fear of Negative Evaluation scale, and the Achievement via Independence/via Conformance scales. Obtained results demonstrated that internals were academically superior to both defensive and congruent externals. Defensive externals were shown to have higher grade point averages than congruent externals, and female defensive externals achieved greater academic success than their male counterparts. Further results suggested that the relationship between locus of control and academic performance may not be a direct one but may be modified by specific mediating variables.     

Stress, externality, and depression

Previous research has found mixed support for the possibility that locus of control moderates the effects of life stress on depression. Two methodological choices may have influenced previous findings: the use of a unidimensional rather than a multidimensional locus of control scale, and reliance on linear statistical methods using median splits. We attempted to correct these choices by using the Levenson IPC scale (1974) and multiple regression analyses in a female undergraduate population (N = 158). The results supported use of a multidimensional scale, since Stress, Internality, and Powerful Others were found to have main effects on depression whereas Chance interacted with life stress. The question of whether locus of control refers to responsibility for causing an event, i.e., self-blame, or belief in control over future events, i.e., coping behavior, was discussed.     

A Comparison of Two Multidimensional Health Locus of Control Instruments

This study examined the factor structure, internal consistency reliability and construct validity of the multidimensional health locus of control (MHLC) instruments developed by K. A. Wallston, B. S. Wallston, and DeVellis (1978) and Lau (Lau, 1982; Lau & Ware, 1981), Both measures were administered to a sample of Veterans Administration (VA) medical outpatients (N = 181). Only minimal evidence of convergence was found between corresponding scales of the two MHLC instruments. Low convergent validity appears attributable to the poor internal consistency reliability of the Lau-Ware subscales. Moreover, results of factor analysis largely supported the a priori factor structure of the K. A. Wallston et at. (1978) MHLC instrument but failed to support the factor structure of the Lau-Ware instrument, Health locus of control (HLC) dimensions that emerged from simultaneous factor analysis of both instruments were most consistent with a three-dimensional typology (i.e., Personal Control, Professional Control and Chance) rather than the four-dimensional typology proposed by Lau (Lau, 1982; Lau & Ware, 1981). Implications for HLC conceptualization and measurement are discussed.

Suicidal Ideation, Depression, and Conduct Disorder in a Sample of Adolescent and Young Adult Twins

The co-occurrence of suicidal ideation, depression, and conduct disturbance is likely explained in part by correlated genetic and environmental risk factors. Little is known about the specific nature of these associations. Structured interviews on 2,814 twins from the Virginia Twin Study of Adolescent Behavioral Development (VTSABD) and Young Adult Follow-Up (YAFU) yielded data on symptoms of depression, conduct disorder, and adolescent and young adult suicidal ideation. Univariate analyses revealed that the familial aggregation for each trait was explained by a combination of additive genetic and shared environmental effects. Suicidal ideation in adolescence was explained in part by genetic influences, but predominantly accounted for by environmental factors. A mixture of genetic and shared environmental influences explained ideation occurring in young adulthood. Multivariate analyses revealed that there are genetic and shared environmental effects common to suicidal ideation, depression, and conduct disorder. The association between adolescent suicidal ideation and CD was attributable to the same genetic and environmental risk factors for depression. These findings underscore that prevention and intervention strategies should reflect the different underlying mechanisms involving depression and conduct disorder to assist in identifying adolescents at suicidal risk.

A study of genetic and environmental effects on the co-occurrence of problem behaviors in three-year-old twins

The authors examined the genetic and environmental causes of the co-occurrence of problem behaviors in children. The analyses involved mother and father ratings of Oppositional, Withdrawn/Depressed, Aggressive, Anxious, Overactive, and Sleep Problems in 446 monozygotic and 912 dizygotic pairs of 3-year-old twins. Genetic factors contributed on average .150 (37.3%), shared environment .206 (51.2%), and nonshared environment .046 (11.4%) to the phenotypic correlations between the syndromes. Genetic and environmental factors caused different groupings. Internalizing and Externalizing groupings were indicative of nonshared environmental factors; clusters of problem behaviors with either the Aggressive or Anxious symptoms were most suggestive of genetic factors, and high scores on all syndromes indicated shared environmental influences.
