Caregiver interactions with autistic children

Caregiver interactions with young autistic children were contrasted with those involving caregivers and developmentally matched mentally retarded and normal infants. Caregivers of autistic children were similar to other caregivers in their responsiveness to child nonverbal communication bids and in their engagement in mutually sustained play. Caregivers of autistic children were similar to caregivers of mentally retarded children in their greater use of control strategies. However, these two groups of caregivers differed in the particular strategies they used to shape their children's behavior. Caregivers of mentally retarded children pointed to objects while caregivers of autistic children spent more time physically holding their children on task. Individual differences within the autistic sample indicated that caregivers regulated their children's behavior less and showed more mutual play and positive feedback to more communicatively able autistic children. These findings suggest that caregivers respond differentially to the specific deficiencies shown by their children.     

Humor and the coronary-prone behavior pattern

The belief is widely held that humor is related to recovery from, and perhaps an increased resistance to, coronary and other stress-related diseases. Such generalizations do not typically distinguish between benign and hostile humor. In the present research, the relationship between a measure of proneness to coronary heart disease (CHD) and appreciation of hostile and nonhostile humor is examined. In two studies, one with college students and one with patients suffering from CHD, the relationship between humor preferences and the coronary-prone (Type A) behavior pattern was examined. Each subject was given the Jenkins Activity Survey as a measure of the coronary-prone personality type, and aggressive and nonaggressive jokes to rate for funniness. Hostile humor was preferred to nonhostile humor by all groups, but among those suffering from CHD, those who could be classified as “Type B’s” preferred nonhostile humor. The results indicate that those less prone to CHD appreciate both hostile and nonhostile humor, while Type A’s seem to enjoy hostile humor only.     

Abnormal and normal obsessions: a reconsideration

Contemporary cognitive approaches to obsession assume that the content of clinical obsessions does not differ from non-clinical obsessive intrusions. This assumption goes back to a classic study by Rachman and De Silva [(1978). Abnormal and normal obsessions. Behaviour Research and Therapy, 16, 233-248]. In the present paper, it is argued that Rachman and De Silva did not postulate a complete indifference between clinical and non-clinical obsessions. Study 1 is a simple statistical analysis of data presented by Rachman and De Silva. This analysis suggested that psychologists are able to discriminate clinical and non-clinical obsessions beyond chance level, merely by looking at the content of obsessions. In study 2, a list of 23 clinical and 47 non-clinical obsessions was presented to 11 psychotherapists and 90 psychology undergraduates. Both therapists and students were able to distinguish clinical and non-clinical obsession beyond chance level. It is concluded that some clinical obsessions can be identified as being evidently abnormal, and that additional theory and research is needed to identify the causes of these recognisable obsessions.     

Patterns of attachment and parents' adjustment to the death of their child

The impact of adult attachment on psychological adjustment among bereaved parents and the mediating effect of relationship satisfaction were examined among a sample of 219 couples of parents. Data collection took place 6, 13, and 20 months after loss. Use of the actor partner interdependence model in multilevel regression analysis enabled exploration of both individual as well as partner attachment as predictors of grief and depression. Results indicated that the more insecurely attached parents were (on both avoidance and anxiety attachment), the higher the symptoms of grief and depression. Neither the attachment pattern of the partner nor similarity of attachment within the couple had any influence on psychological adjustment of the parent. Marital satisfaction partially mediated the association of anxious attachment with symptomatology. Contrary to previous research findings, avoidant attachment was associated with high grief intensity. These findings challenge the notion that the avoidantly attached are resilient.     

A Cognitive Psychophysiological Model to Predict Functional Decline in Chronically Stressed Older Adults

The current study evaluated whether psychological distress (composite of depression, anxiety, vital exhaustion), inflammation (C-reactive protein, CRP) and cognitive function (Digit Symbol Test, DST) and their changes mediated the relationship between caregiver status and functional decline. Caregivers for spouses with Alzheimer’s disease were compared to demographically-similar non-caregiver spouses at study entry (T1), T2 (1 year later), and T3 (2 years after T1). Caregivers had greater functional impairment, higher distress scores, and poorer DST scores at all points of measurement and also showed functional decline. Non-caregivers did not demonstrate functional decline. Caregivers declined 85% faster than did non-caregivers. Regressions showed that after controlling for functional impairment at T1, illness, medication, and health behavior covariates, psychological distress at T1 and increases in CRP from T1 to T3 mediated the difference in functional decline. Moreover, after DST decline from T1 to T2 was entered in the model, caregiver status, psychological distress and increases in inflammation all showed reductions in their predictive importance. These findings suggest psychological distress and increases in inflammation may help explain why caregivers show greater functional decline than non-caregivers. However, the influences of these psychophysiological variables may be driven in part by cognitive decline prior to functional decline. This article is based upon an invited address, “Potential Hazards of Caring for a Loved One with Alzheimer’s Disease” given by the first author in recognition of the author’s receipt of the Association of Psychologists in Academic Health Centers 2005 Award for Distinguished Achievement in Research. The address was presented at the Annual meeting of the American Psychological Association, New Orleans, LA., August, 2006.     

Examination of the MMPI-2 Restructured Clinical (RC) Scales in a Sample of Bariatric Surgery Candidates

The current study examined the MMPI-2 Restructured Clinical (RC) scales (Tellegen et al., MMPI-2 Restructured Clinical (RC) scales: Development, validation, and interpretation. Minneapolis: University of Minnesota Press, 2003) in a sample of 1,091 bariatric surgery candidates. The RC scales were developed to address concerns about limited discriminant validity of the Clinical scales. Internal consistency and external validity analyses were conducted to evaluate the RC scales in this setting. Results indicated that the RC scales are generally more internally consistent than the Clinical scales and display significantly better convergent and discriminant validity in predicting a variety of behavioral, psychological, and developmental variables relevant to preoperative bariatric psychological evaluations. Implications of the results and recommendations for future research with the RC scales in medical settings are discussed.
