Dynamic role of social support in the link between chronic stress and psychological distress.

How a chronic environmental stressor can interfere with the buffering effects of social support by eroding social support was analyzed in this prospective, longitudinal study. A classic buffering effect of support was found after 2 months of exposure to the stressor, household crowding. Crowded residents with low perceived support had greater increases in psychological distress than did crowded residents with high perceived support. However, after 8 months exposure the buffering effect disappeared. Moreover, greater crowding had become directly associated with lower support, which in turn was associated with greater increases in psychological distress. All analyses controlled for prior distress. Under some types of chronic stress, the buffering effects of social support may be short-lived because the stressor eventually erodes social support.     

An examination of the construct validity of the Social Anhedonia Scale

Two studies bearing on the construct validity of the Social Anhedonia Scale (SA) are reported. Study 1 reported convergent validity coefficients between the SA scale and numerous measures of traits reflecting a generalized attitude toward others (e.g., social interest and empathy) as well as several traits reflecting maladjustment without a social component as a test of discriminant validity (e.g., pessimism and rigidity). Study 1 found impressive convergent validity for the SA scale and mixed discriminant validity. Study 2 found that the SA scale was related to two dimensions of striving for security, one of which is strongly influenced by negative interpersonal tendencies, suggesting support for the validity of the SA scale. Implications for the measurement and concept of social anhedonia are presented.     

Hopelessness in community-residing aged persons: a viable construct?

Previous work with the Geriatric Hopelessness Scale (GHS; Fry, 1984, 1986) suggests that it may be a useful measure of pessimism for a variety of domains among elderly persons. One hundred seven community-residing aged persons were individually administered the GHS and a variety of personality and cognitive functioning measures in an effort to further refine and validate the GHS. Results suggest very modest internal consistency and a poorly defined factor structure for the GHS, in contrast to earlier findings. Although the GHS failed to differentiate elderly persons by age, it was nonetheless related to self-esteem, depression, self-rated health, internality, morale, and life satisfaction. Taken together, these data indicate that the research and clinical utility of the GHS with community-residing aged persons may be more limited than previously believed.     

A multidimensional analysis of internal health locus of control beliefs: separating the wheat from the chaff?

The current study examined the hypotheses that internal health locus of control comprises multiple dimensions and that these dimensions are differentially associated with physical health status. As expected, using covariance structure modeling of data derived from 181 medical outpatients, internal health locus of control was found to be multidimensional. Predicted dimensions included recognition that illness prevention is contingent on successful execution of potential health actions, recognition that illness management is contingent on successful execution of potential health actions, and self-mastery over health outcomes (i.e., the perceived capacity to achieve desired health outcomes). A 4th dimension (i.e., self-blame for negative health outcomes) also emerged. Moreover, as predicted, only perceptions of self-mastery were independently associated with indexes of physical health and well-being.     

Three methods of developing MMPI taxonomies of sexual offenders

In a sample of 261 state hospital sexual offenders, Minnesota Multiphasic Personality Inventory (MMPI) profiles did not differ for offenders with adult victims versus offenders with child victims when offender age was controlled. MMPI 2-point analyses for the whole sample revealed five common codes that were independent of victim maturity. The sample was randomly divided in half and subjected to a cluster-analytic procedure which revealed two MMPI clusters. The first cluster was unelevated, with Scale 4 as its high point. The second cluster had multiple elevations, with Scales 8, 4, 2, and 7 as the highest scales. These clusters were replicated in a cluster analysis of the second half of the sample. However, when the sample was recombined, the two clusters were not externally validated basis on demographic and criminological variables. The results suggest that common psychological variables among sexual offenders may have more discriminative value than victim maturity in developing sexual offender taxonomies.     

Assessment of attention deficit disorder using a thematic apperception technique

Attention deficit-hyperactivity disorder (AD-HD) is regarded as being relatively common among school-age children, but the literature reveals a number of confounding factors with standard assessment techniques of the disorder. Using a structured thematic apperception technique (the Tell-Me-A-Story [TEMAS] test) to measure attention to pictorial stimuli depicting characters, events, settings, and covert psychological conflicts, a study was conducted with 152 normal and 95 clinical Hispanic, Black, and White school-age children. Results reveal that the AD-HD children are significantly more likely than normal children to omit information in the stimuli about characters, events, settings, and psychological conflicts. Differences between the groups are large and persistent in the presence of structured inquiries by the test examiners. Results suggest the potential utility of structured thematic apperception techniques for the assessment of AD-HD, eventually to facilitate DSM-III-R (American Psychiatric Association, 1987) diagnosis, but also to invite closer scrutiny in carefully controlled validity studies.     

Dimensions of self-concept of pregnant unwed teens

The study examined the self-esteem of pregnant teens enrolled in a program designed to maximize their chances of completing school. The Culture Free Self-Esteem Inventory (Battle, 1981) and the Coopersmith (1981) Self-Esteem Inventory were completed by the teens. The mean score of the group on the Culture Free Total Self Scale was below average in comparison to the norm.     

Research on the clinical usefulness of the Rorschach: 2. The assessment of cerebral dysfunction

A review of research on the use of the Rorschach in the assessment of cerebral dysfunction indicated that the Rorschachs of patients with cerebral dysfunction do not manifest any characteristic response in terms of percentages, ratios, or any unique response to any one of the stimulus determinants of the blots (color, shading, the stimulus for movement). The patient with cerebral dysfunction does manifest a unique style of thinking; responses tend to be concrete, perseverative, and stereotypic. This finding is similar to that found with schizophrenics where research, summarized by Frank in 1990, also indicated no uniquely 'objective' response style but reflected a unique cognitive style. These two reviews taken together suggest that the better way to use Rorschach data in clinical work is as an opportunity to assess patients' thinking as opposed to the Rorschach being used as a psychometric device, yielding 'numbers.'     

Attentionally splitting the mass distribution of hand-held rods

Two experiments on the length-perception capabilities of effortful or dynamic touch differed only in terms of what the subject intended to perceive, while experimental conditions and apparatus were held constant. In each trial, a visually occluded rod was held as still as possible by the subject at an intermediate position. For two thirds of the trials, a weight was attached to the rod above or below the hand. In Experiment 1, in which the subject's task was to perceive the distance reachable with the portion of the rod forward of the hand, perceived extent was a function of the first moment of the mass distribution associated with the forward portion of the rod, and indifferent to the first moment of the entire rod. In Experiment 2, in which the task was to perceive the distance reachable with the entire rod if it was held at an end, the pattern of results was reversed. These results indicate the capability of selective sensitivity to different aspects of a hand-held object's mass distribution, without the possibility of differential exploration specific to these two tasks. Results are discussed in relation to possible roles of differential information, intention, and self-organization in the explanations of selective perceptual abilities.
