Assessment of the life stress-depression relationship: The use of social support as a moderator variable

The Moderating Role of Social Support on the Relationship Between Impulsivity and Suicide Risk

Background: Suicide is the second leading cause of death among college students. There has been considerable research into risk factors for suicide, such as impulsivity, but considerably less research on protective factors. Aims: The present study examines the role that social support plays in the relationship between impulsivity and suicide risk. Methods: Participants were 169 undergraduates who completed self-report measures of impulsivity and social support. Suicide risk was assessed using an interview measure. Results: Social support moderates the relationship between impulsivity and suicide risk, such that those who are highly impulsive are less likely to be at risk for suicide if they also have high levels of social support. Conclusions: Social support can be a useful buffer to suicide risk for at-risk individuals who are highly impulsive.

Life stress and social supports in depressed inpatients

The presence of adequate social supports has been associated with a reduced incidence of psychological symptoms. It is unclear, however, whether the protective influence of social supports is because of a direct positive effect on psychological functioning or a stress-buffering effect. Furthermore, most research on life stress and social supports has focused on community-based rather than clinical samples. The present study attempts to clarify the relationship between life stress and social supports related to psychological symptoms in 84 adult, nonpsychotic, depressed inpatients. Subjects were categorized according to their responses on the Life Experiences Survey and the Social Supports Inventory. Subjects were then assessed using both structured interviews and self-report measures of depression and suicide potential, as well as other psychological symptoms. Although both life stress and social supports were significantly related to a variety of psychological symptoms, the interaction between these variables was not significantly related to psychological symptomatology. Life events and social supports were found to exert their effects independently. This argues against the stress-buffering theory in favor of the direct-effects theory of social supports, at least when applied to inpatient samples.

Adolescent mothers, stress, and prevention

Adolescent mothers face problems that can lead to psychological stress. Based on prospective data from the present study, these problems point toward the need for a coping skills prevention approach to help adolescent mothers manage stress. This paper reports data from outcome research on such an approach with adolescent mothers. Subjects were 79 adolescent mothers who were tested before, immediately after, and three months following the provision of coping skills intervention in an experimental condition. Subjects in a test-only control condition received no special intervention. At posttest, experimental condition subjects showed more positive outcomes on measures of social support, cognitive performance, conflict management, and interpersonal competence. At three-month follow-up, experimental condition subjects had more positive outcomes on social support, cognitive performance, parenting ability, child care self-efficacy, and measures of psychological well-being.

Multivariate evaluation of health attitudes and behaviors: development and validation of a method for health promotion research

Many self-reported measures of health status, attitudes, and knowledge used by clinicians and researchers suffer from a variety of shortcomings, including limited empirical justification, excessive complexity, assessments of nonmodifiable historic or hereditary factors, and limited utility for public health program planning. The Health Attitudes and Behavior Scale is an instrument designed to overcome many of these shortcomings and direct public health professionals toward more efficacious interventions. One hundred sixty-four subjects responded to true-false and Likert scale items related to health beliefs, attitudes, and behavioral practices. A principal component analysis of the Likert items yielded six components, tentatively labeled (a) Lack of Social Support, (b) Hurdles to Health, (c) Health Attitudes/Weight Concerns, (d) Positive Environment, (e) Disease Concerns, and (f) Time and Work Pressure. Analyses of these scales using coefficient alpha indicated adequate internal consistency for each of them. These scales were then related to demographic variables of age, educational level, sex, and marital status. Next, these scales were correlated with individual true-false items reflecting self-reported behavioral practices or health histories. A component analysis of the true-false items yielded four principal components labeled (a) Organizational Health Concerns, (b) Smoking and Exercise Concerns, (c) Coronary and Weight Concerns, and (d) Blood Pressure and Risk Factor Programs. Finally, a cluster analysis yielded six typical profiles reflecting different levels of the original six components. Of interest is the fact that the Lack of Social Support and Time and Work Pressure scales had a very limited integration into the overall patterns. The assumption that organizational and environmental factors can have an important impact on health was supported. The need for further research in this area is also discussed.

Social intimacy: an important moderator of stressful life events

Two studies were conducted to explore the role of social intimacy in predicting the individual's response to stress. In the first study the experimenter reinforced the experimental subjects' verbalizations during an interview on a fixed schedule for the first 3 minutes, withdrawing reinforcement for the final 4 minutes. The control group received reinforcement on a fixed schedule for the total 7 minutes. Subjects scoring low on a measure of intimacy disclosed less personal material during the withdrawal period in the experimental condition than in the control condition in contrast to high scoring subjects who maintained their level of disclosure for both parts of the interview. In the second study, previously experienced life change events were assessed. Individuals lacking a current intimacy were found to be prone to higher levels of emotional disturbance especially when many previous negative or few positive life change events had occurred.
