Locus of Control Orientation Among Obese Adults in Outpatient Treatment for Obesity

We studied locus of control (LOC) in samples of obese and nonobese subjects. We administered Rotter's (1966) I-E Scale to 106 obese adults in outpatient treatment for obesity and to 99 nonobese controls. The obese subjects were significantly more internally oriented than the control group. These findings challenge currently held assumptions on the directionality of LOC in obese groups. The results contradict the consensus among researchers that obese individuals have an external LOC orientation. The finding that internal LOC is associated with the obese condition may be a useful predictor variable influencing obesity treatment, approaches, and outcome.     

Control orientation as a personality dimension among alcoholic and obese adult men undergoing addictions treatment.

Rotter's (1966) I-E Locus of Control Scale was administered to 18 men in residential treatment for alcoholism and 13 men in intensive outpatient treatment for obesity. The obese sample scored significantly higher in internal locus of control, whereas the alcoholic sample was comparatively external in control orientation. These findings contradict currently held assumptions on the directionality of control orientation among both alcoholic and obese adults and suggest that internally oriented obese adults may feel that they have little control over their weight and eating behavior but more control over other aspects of their lives. In contrast, externally oriented alcoholics appear to be aware of their inability to control their drinking and their limited control over many factors influencing their lives. Implications for treatment are also discussed.     

Differences in locus of control between obese adult and adolescent females undergoing weight reduction

Rotter's (1966) Internal-External (I-E) Scale was administered to 65 adult and adolescent females in two outpatient obesity treatment programs. The adults were significantly higher in internal locus of control (LOC) and the adolescents higher in external LOC. These differences suggest that although the adults felt limited control over their weight and eating behavior, this did not reflect a lack of perceived control over other factors in their lives. In contrast, the adolescents appeared to feel that they had limited control over an array of factors in their lives.     

Control Orientation as a Personality Dimension Among Alcoholic and Obese Adult Men Undergoing Addictions Treatment

Rotter's (1966) I–E Locus of Control Scale was administered to 18 men in residential treatment for alcoholism and 13 men in intensive outpatient treatment for obesity. The obese sample scored significantly higher in internal locus of control, whereas the alcoholic sample was comparatively external in control orientation. These findings contradict currently held assumptions on the directionality of control orientation among both alcoholic and obese adults and suggest that internally oriented obese adults may feel that they have little control over their weight and eating behavior but more control over other aspects of their lives. In contrast, externally oriented alcoholics appear to be aware of their inability to control their drinking and their limited control over many factors influencing their lives. Implications for treatment are also discussed.     

The relationship among the transtheoretical model of behavioral change,psychological distress,and diet attitudes in obesity: Implications for primary care intervention

Obesity is prevalent but undertreated in primary care. Family practice volunteer outpatients (N=454) were administered the Stage of Change for Weight (URICA), the Brief Symptom Inventory (BSI), and the Diet Readiness Test (DRT) to assess the relationship between these variables and obesity. The body mass index (BMI) was used to classify obesity revealing 197 patients with elevated BMI's. There was no significant difference between the obese and the nonobese on any of the psychological measures. The obese reported significantly more difficulty setting diet goals and less control over their eating, ate more to emotional situations, and exercised less than the nonobese. The obese sample (46.7%) reported being in the Action stage of change for weight management. Implications for intervention in primary care include targeting attitudes (DRT) and dispelling physician attitudes that obese individuals have increased levels of psychological distress. Addressing Stage of Change for weight management can facilitate tailoring the appropriate intervention when used in concert with the DRT variables.     

Validity of the Internal-External Scale in Its Relationship with Political Position

The study was designed to interpret previous reports of a relationship between left wing political position and externality on Rotter's (1966) Internal-External (I-E) Scale. I-E items phrased in the first person were associated with a criterion measure of locus of control, and externality on the scale predicted inferior performance in a skill-controlled task. However, political position was related to neither the criterion measure of locus of control nor to successful performance in a skill-controlled task. Thus, there was no evidence that political position was related to locus of control in spite of its relationship with the I-E Scale. There was discussion of implications for the validity of the I-E Scale and for studying relationships between personality and political variables.     

Dimensionality and Adjustment Correlates of Locus of Control Among Hong Kong Chinese

The Chinese version of Rotter's Internal-External Locus of Control (I-E) Scale was administered to a sample of 94 Hong Kong Chinese undergraduates. Three dimensions interpretable as Personal Powerlessness, General versus Specific (Situational/Interpersonal) Powerlessness, and Political Powerlessness emerged. Scores derived from these empirical dimensions, however, yielded only modest improvement over the total score in predicting psychological symptoms as assessed by the General Health Questionnaire (GHQ). Although the Hong Kong Chinese were found to be more external in general luck or fate, they manifested a belief in internal control in specific domains of achievement and interpersonal relationships.     

Validity of the Internal-External Scale in its relationship with political position

The study was designed to interpret previous reports of a relationship between left wing political position and externality on Rotter's (1966) Internal-External (I-E) Scale. I-E items phrased in the first person were associated with a criterion measure of locus of control, and externality on the scale predicted inferior performance in a skill-controlled task. However, political position was related to neither the criterion measure of locus of control nor to successful performance in a skill-controlled task. Thus, there was no evidence that political position was related to locus of control in spite of its relationship with the I-E Scale. There was discussion of implications for the validity of the I-E Scale and for studying relationships between personality and political variables.     

Body weight and bulimia as discriminators of psychological characteristics among anorexic, bulimic, and obese women

Bulimic women from underweight (n = 20), normal-weight (n = 31), and overweight (n = 22) categories were compared with restrictor anorexics (n = 20), normal controls (n = 31), and obese subjects (n = 22). Each subject was administered the Minnesota Multiphasic Personality Inventory, the Internal-External Locus of Control Scale, the Rosenberg Self-Esteem Scale, and the Semantic Differential Potency Scale. Bulimic women in all 3 weight categories exhibited greater psychopathology, more external locus of control, lower self-esteem, and lower sense of personal effectiveness than nonbulimic women at similar weight levels. The highest psychopathology, lowest self-esteem, and most external locus of control were found among the underweight bulimic women. Significant differences between bulimic women of different weight levels suggest the need for some modification of treatment approaches depending on the bulimic women's weight level.     

Unidirectional Mazes for Studying Human Learning

The purpose of this study was to determine if academic performance affects locus of control scores. Twenty-one college students were randomly assigned to either a treatment or control group by sex. The treatment group received mnemonic training enabling them to score better than the control group. The treatment group had significantly more internal scores than the control group with the Rotter Locus of Control Scale but not with the Nowicki-Strickland I-E Scale.     

Cultural Conflict and the Feminine Role: An Experimental Study

Summary

Levenson's multidimensional I-E Scale was administered to 625 male and female university students and adults in America and Greece. The scores were categorized by sex, country, and employment status (job-holding adults or students) on each of the three control dimensions and then subjected to 2 × 2 × 2 analyses of variance. There were no significant sex main effects for any of the three I-E dimensions, thus calling into question previous cross-cultural findings that women were more external than men. Americans and Greeks did not differ on the Personal Control dimension, but Greeks did believe that they live in a more unpredictable environment than the Americans and also one in which powerful others control their outcomes. The results also indicated that students report having less of a sense of responsibility for their own actions than adults, but the two groups did not differ significantly on the Powerful-others or Chance dimensions. Finally, differences in the patterns of scoring across I-E content areas among subjects suggested the usefulness of utilizing a multidimensional I-E scheme in future cross-cultural personality research.     

Locus of control and effects of perceptual tasks on heart rate

The hypothesis was tested that the relationship found in prior research between heart rate changes produced in biofeedback settings and locus of control scores derives from the heart-brain relationship described by the Laceys in 1967, as well as from "expectancies for control." 48 subjects were tested on two perceptual tasks known to elicit changes in heart rate. Significant heart rate changes were observed in response to both tasks, but those changes did not correlate with locus of control as measured by scores on the Rotter I-E Scale and the Multidimensional Health Locus of Control Scale. Explanations for these results are offered.     

The Relationship Between Childhood Onset Obesity and Psychopathology in Adulthood

We administered the Symptom Checklist (Derogatis, 1975; SCL-90-R) to 37 obese subjects in outpatient treatment for obesity. Patients with early onset obesity demonstrated a greater frequency and higher levels of emotional distress and psychiatric symptomatology than patients with late onset obesity. Individuals who developed obesity in childhood showed more psychopathology than those who developed obesity later in life. Overall, these findings support the belief that obesity is characteristically associated with greater internal psychological conflict. These findings further suggest that childhood obesity could serve as a predictor variable for possible future psychological disturbance in obese populations.     

College students who wear watches: locus of control and motivational sources

119 undergraduate college students were administered the Rotter I-E Scale and the Motivation Sources Inventory. Scores were compared for a group of 66 students who were wearing watches and 53 students who were not wearing watches. The former had higher scores on External locus of control and higher scores on a measure of Instrumental Motivation as anticipated.     

Social Interactions of Obese and Nonobese Women

The stigma associated with obesity is likely to limit the opportunities obese women have to develop social skills. This hypothesis was tested by having obese (n = 15) and nonobese (n = 22) women converse on the telephone with college students who were unaware of the women's weights. Ratings made by judges who listened to the women's contributions to the conversations but who were unaware of their weights showed that obesity was negatively related to judgments about the women's likability, social skills, and physical attractiveness. The telephone partners of obese women rated the women and themselves more negatively than did the partners of nonobese women. Obese and nonobese women generally did not differ in their evaluations of their own and their telephone partners' behavior, and they also did not differ on a measure of social self-esteem. These findings suggest that there are real differences in the social behavior of obese and nonobese women and that these differences affect the impressions formed by those with whom they interact.     

The Effect of Locus of Control on University Students' Mental Health: Possible Mediation through Self-Esteem and Coping

The purpose of this study was to examine the effect of locus of control on university students' mental health and to examine possible mediational roles of self-esteem and coping. A total of 418 university students completed Rotters I-E Scale, Self-liking/self-competence Scale, Endlers Coping with Stressful Situations Scale and Depression, Anxiety and Stress Scale. The results showed that external locus of control, lower self-liking and self-competence, as well as less problem-focused and more emotion-focused coping predict more symptoms of depression, anxiety, and stress in university students. However, mediational analysis revealed that the effect of locus of control was fully mediated by self-esteem and coping, with self-liking and emotion-focused coping being the strongest mediators. Results suggest that beliefs about control affect beliefs about one's self-worth and coping strategies, which in turn can affect one's mental health.     

Daydreaming: a measurable concept

Research has been reported which supports the psychometric properties of the Imaginal Processes Inventory. The purpose was to confirm and extend this research as well as investigate the interrelationships between daydreaming and depression, locus of control, and visual imagery. This inventory (7 scales), Beck Depression Inventory, Rotter Locus of Control Scale (I-E), and Gordon's Test of Visual Imagery Control were administered to 100 female undergraduates. A sample of 39 subjects were retested on the scales an average of 6.8 wk. after the first administration. Correlations with Imaginal Processes Inventory and test-retest data were consistent with Giambra's (1977) findings for males and support the reliability and generalizability of the scores. Other results include significant intercorrelations between the various scales of this inventory and the others. Implications for an understanding of the process of depression are discussed.     

Cross-national stereotypes of locus of control in university students1

Stereotypes of locus of control were studied in male and female university students from eight countries (Canada, France, West Germany, India, Israel, Italy, Japan, United States). The subjects took the Rotter Internal-External Locus of Control (I-E) Scale in standard fashion (“own” scores) and then in the role of students similar to themselves in their own country (attributed own) and in selected other countries (attributed other). Using the difference between “own” scores and “attributed” scores as the operational measure of stereotype, the results indicate (1) that scores attributed to students in a given country bear little relationship to those students “own” scores, thereby suggesting the presence of stereotypes of locus of control; (2) students in most countries attribute greater externality to the average student in their own country compared to themselves; (3) countries vary in the degree to which they stereotype other countries with the U.S. students significantly attributing greater externality to other countries and Japanese students significantly attributing greater internality to other students; (4) countries vary in the degree to which they are stereotyped with German students perceived as most internal and Italian students as most external; (5) the U.S.S.R. and U.S.A. are perceived differently on content subscales of the I-E Scale although their overall attributed scores do not differ.     

The Dimensionality of Locus of Control Among French Students

To learn more about the dimensionality of locus of control, I developed a new internal-external (I-E) scale for French students. Four criteria were used for the construction of the scale: causal explanation and orientation of behavioral outcomes, situational contents, and control ideology. Questionnaires were administered to 200 male and female undergraduates in psychology. A principal-components analysis and a nonmetric multidimensional scaling were used. The hypothesis of the unidimensionality of locus of control was confirmed.     

Relationships Between the CPI, MMPI, and locus of control in a nonacademic environment

Summary: Rotter's Internal-External (I-E) locus of control scale, the MMPI, and the CPI were administered to a sample of 100 males heterogeneous in age and education level. Relationships between I-E and the other measures were examined and a substantial number of significant correlations were found. Considerable variance in I-E scores could be accounted for by similar variance in MMPI and CPI responses, but a discriminant analysis failed to enable reliable predictions of I-E from other scales. The findings qualify the interpretation of correlational relationships found in previous research concerning I-E and suggest specific directions for future investigations.
