Effects of parental alcoholism and life stress on hispanic and non-hispanic caucasian adelescents: A prospective study

Investigated ethnicity and parental alcoholism as factors that might influence the stress vulnerability of adolescents. It extended an initial cross-sectional study of this same sample by adding two annual assessments which allowed for additional cross-sectional analyses and longitudinal tests. Hispanic and Caucasian adolescents (N=306 at Time 1) completed measures of their own life stress, family conflict, and alcohol use. Their parents reported on adolescents' internalizing and externalizing symptoms. Cross-sectional analyses at Time 2, and prospective analyses involving Time 1 and Time 2 measures were, for the most part, consistent with the original study's results. Caucasian adolescents and children of alcoholic parents appeared to be more vulnerable to stress than Hispanic adolescents and children of nonalcoholic parents. Family conflict was a partial explanation for this increased vulnerability. This research was supported by National Institute on Drug Abuse Grant DA05227 to Laurie Chassin (pricipal investigator) and Manuel Barrera, Jr. (coprincipal investigator). Susan Li was supported by an American Psychological Association Minority Fellowship Award. Portions of this research were presented at the conference, “Resiliency in Families: Racial and Ethnic Minority Families in America” that was held at the University of Wisconsin, May 31–June 2, 1994.     

Analysis of long-term stress reactions in emergency room patients: An initial study

The psychological stress reactions of 44 family medicine patients who were treated in the emergency room were examined approximately a year after the event. Patients were assessed on several psychological measures, including one for posttraumatic stress disorder (PTSD), and on their perception of how stressful the event was initially and now. Results show continuing stress reactions related to the emergency room event. Three patients endorsed symptoms indicating full PTSD and 13 appeared to have at least partial PTSD. Age appeared to be a factor in the presence of stress symptoms and in degree of perceived communication with the physician.     

Parenting stress in parents of children with attention-deficit hyperactivity disorder and parents of children with learning disabilities

Parenting a child with ADHD can challenge parenting resources and coping. Increasingly, researchers are examining the relationship between the behavior of the child with ADHD and family functioning. While studies have shown inceased parenting stress in parents of children with ADHD, these studies have compared children with ADHD to non-disabled children. This study compares reports of parenting stress among mothers of children with ADHD, mothers of children with learning disabilities and mothers of non-referred children. Results showed that parenting stress was highest for mothers of children with ADHD. Increased parenting stress was associated with child characteristics and, in particular, with externalizing behavior problems.     

Cognitive Functioning in Treatment-Seeking Gulf War Veterans: Pyridostigmine Bromide Use and PTSD

Gulf War (GW) deployed veterans have reported health symptoms since returning from the war that suggest dysfunction of the central nervous system (CNS). These symptoms include memory and concentration difficulties, fatigue, and headaches. Leading hypotheses for the etiology of these cognitive complaints include psychological factors and/or exposures to chemicals with neurotoxic properties. In this study, cognitive functioning was compared in treatment-seeking GW-deployed veterans and a treatment-seeking non–GW-deployed veteran control group. Results indicated that GW-deployed veterans performed significantly worse than the comparison group on tests of attention, visuospatial skills, visual memory, and mood. GW-deployed veterans who reported taking pyridostigmine bromide (PB) performed worse than GW-deployed veterans without PB use on executive system tasks. Treatment-seeking GW-deployed veterans with diagnoses of posttraumatic stress disorder (PTSD) did not differ on cognitive test measures compared with GW-deployed veterans without PTSD. No interaction effect of PTSD and PB use was found.     

Are Individuals Always Aware of Their Trauma-Related Intrusive Thoughts? A Study of Meta-Awareness

Individuals are not always aware of their mental content. We tested whether lack of awareness occurs in those who have experienced trauma, with and without posttraumatic stress disorder (PTSD). We also examined the role of proposed cognitive mechanisms (working memory and inhibition) in explaining unnoticed intrusions. Individuals with PTSD (n = 44), and varying levels of symptoms (high posttraumatic stress [PTS]: n = 24; low PTS: n = 37) reported on intrusive thoughts throughout a reading task. Intermittently, participants responded to probes about whether their thoughts were trauma related. Participants were “caught” engaging in unreported trauma-related thoughts (unnoticed intrusions) for between 24 and 27% of the probes in the PTSD and high PTS groups, compared with 15% of occasions in the low PTS group. For trauma-related intrusions only, participants lacked meta-awareness for almost 40% of probes in the PTSD group, which was significantly less than that observed in the other groups (～60%). Contrary to predictions, working memory and response inhibition did not predict unnoticed intrusions. The results suggest that individuals who have experienced significant trauma can lack awareness about the frequency of their trauma-related thoughts. Further research is warranted to identify the mechanisms underpinning the occurrence of unnoticed intrusions.     

Cognitive behaviour therapy of acute stress disorder: a four-year follow-up

The aim of this study was to index the long-term benefits of early provision of cognitive behavior therapy to trauma survivors with acute stress disorder. Civilian trauma survivors (n = 80) with acute stress disorder were randomly allocated to either cognitive behavior therapy (CBT) or supportive counseling (SC) - 69 completed treatment, and 41 were assessed four years post-treatment for post-traumatic stress disorder (PTSD) with the Clinician Administered PTSD Scale. Two CBT patients (8%) and four SC patients (25%) met PTSD criteria at four-year follow-up. Patients who received CBT reported less intense PTSD symptoms, and particularly less frequent and less avoidance symptoms, than patients who received SC. These findings suggest that early provision of CBT in the initial month after trauma has long-term benefits for people who are at risk of developing PTSD.

A measure of parental stress in mothers with small children: dimensionality, stability and validity

Self-reported parental stress was investigated in three samples of mothers with small children, using a Swedish version of the Parenting Stress Index (PSI). Dimensionality in experienced stress using items from six PSI Parent Domain subscales and eight new items was examined in factor analyses of data from a nationwide representative sample. Cross-validation proved the chosen factor pattern to be stable. Based on an oblique 5-factor solution new subscales were constructed. A second order factor analysis indicated influence from a higher order factor, seen as a general parental stress construct. High alpha coefficients revealed that homogeneous subscales had been formed. Test-retest correlations indicated good stability over a mean time period of 30 days. Influences from maternal background variables were found, but no relation to child age or gender. Global estimates of parental stress, reported child problems, mothers' scoring on the Edinburgh Postnatal Depression Scale and two measures of social support all correlated significantly with overall parental stress, and with some subscales. The justification of the subscale approach to parental stress was discussed. It was concluded that the PSI in its present form could be used as a reliable and valid instrument for measuring experienced parental stress in mothers of young children.     

Ambulatory emotional reactivity to negative daily life events predicts remission from major depressive disorder

Major depressive disorder (MDD) is often associated with altered emotional reactivity. However, the functional significance of altered emotional reactivity in MDD is uncertain. This study was the first to examine the predictive relationship between intensely sampled ambulatory emotional reactivity and the clinical course of MDD. Forty-six outpatients who met criteria for MDD underwent six days of experience sampling of their ambulatory reactivity to everyday negative and positive life events. After experience sampling, all outpatients received pharmacotherapy with supportive psychotherapy and were followed clinically for 18 months. At one month, less emotional reactivity to negative and positive daily events predicted higher depressive symptom severity. Importantly, patients who exhibited less negative emotional reactivity to daily negative life events were less likely to recover from MDD over the 18 month follow-up. Relationships between ambulatory emotional reactivity and MDD course were not accounted for by the duration or the severity of initial MDD symptoms. Diminished ambulatory emotional reactivity appears to be functionally significant in depression. Intensive sampling of ambulatory emotions may have utility for predicting the clinical course of MDD.
