Abstract

This paper describes the pilot testing of a survey designed to assess the prevalence of HIV exposure risk-relevant behaviors and associated attitudes, beliefs and knowledge in a heterogeneous, ethnically diverse, sexually active population (the US Army). The specific objectives for the pilot test were to: (1) define optimal survey question formats for behavioral and attitude items; (2) identify questions that were poorly worded or that would not contribute to the overall objectives of the survey; (3) assess the extent to which respondents could accurately follow instructions; (4) identify appropriate and culturally relevant terminology for sensitive items; (5) determine the appropriate timeframe for recall of simple and complex sexual behaviors; (6) assess the degree of respondent honesty and belief in the anonymity of the survey results.  相似文献

The objective of this research was to gain a deeper understanding of factors influencing the healthiness of food choice behaviors of community-dwelling adults with severe mental illness. Semi-structured interviews were conducted in an outpatient treatment facility with 20 program participants and 10 staff. Grounded theory analysis methods were used. Five dominant themes emerged: food availability, preference for simple food preparation, perceived cost of food, complexity of choice, and relative importance of healthy food choices. The theme of medication effects only emerged from staff interviews. This research can be useful to inform the design of nutrition interventions for this population.  相似文献

This exploratory study examined participants in a Family Dependency Treatment Court (FDTC), designed for substance-abusing parents whose children were removed from the home. Twenty-five participants were interviewed one year after FDTC enrollment to assess retrospectively the relationship between trauma history and risky behaviors. Treatment compliance rates were found to be high, and most participants had negative urinalysis results. Qualitative analyses revealed that approximately half of the participants attributed decreases in risky behaviors to the FDTC program. This study increases understanding of the effect of substance abuse and trauma on high-risk behaviors and might help to improve services for substance-abusing parents involved in the child welfare system. Finally, the future success of reducing child abuse and neglect and parental substance use could hinge on the partnership between judicial and substance abuse treatment through FDTCs. Findings from this exploratory pilot study should be replicated with more representative and larger samples.  相似文献

The present study evaluated the efficacy of a brief version of an internet-administered transdiagnostic CBT protocol, the Wellbeing Program (Titov et al., 2011), designed to treat three anxiety disorders and major depression within the same program. This brief version included the same core CBT skills as the original, but condensed the materials from 8 to 5 online lessons, reduced the duration of treatment from 10 to 8 weeks and did not include an online forum. Thirty-two individuals with a principal diagnosis of major depression, generalised anxiety disorder, panic disorder or social phobia received CBT-based online educational lessons, homework assignments, weekly contact from a clinical psychologist and automated emails. Eighty-one percent of participants completed the lessons within the 8 week program. Post-treatment and 3-month follow-up data were collected from 28/32 and 31/32 participants respectively. Participants improved significantly on the Depression Anxiety and Stress Scales – 21 Item, Patient Health Questionnaire – 9 Item, and Generalised Anxiety Disorder – 7 Item scales, with corresponding within-group effect sizes (Cohen’s d) at follow-up of 1.05, .73, and .95, respectively. Participants rated the procedure as highly acceptable with gains of a similar magnitude as those found for the original program, but less time was spent per participant by the clinician in the present trial (mean = 44.61 min, SD = 34.45) compared to the original program (mean = 84.76 min, SD = 50.37). These results provide additional support for the efficacy of transdiagnostic iCBT in the treatment of anxiety and depressive disorders and indicate that a brief version may be of benefit.  相似文献

Each year, an increasing number of children are born through surrogacy and thus lack a genetic and/or gestational link with their mother. This study examined the impact of surrogacy on mother-child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction, and child adjustment were administered to 32 surrogacy, 32 egg donation, and 54 natural conception families with a 7-year-old child. No differences were found for maternal negativity, maternal positivity, or child adjustment, although the surrogacy and egg donation families showed less positive mother-child interaction than the natural conception families. The findings suggest that both surrogacy and egg donation families function well in the early school years.  相似文献

The ability to learn a route through a virtual environment was assessed in 19 older children and adults with Williams syndrome (WS) and 40 typically developing (TD) children aged 6-9 years. In addition to comparing route-learning ability across groups, we were interested in whether participants show an adult-like differentiation between "useful" and "less useful" landmarks when learning a route and the relative salience of landmark position versus landmark identity. Each virtual environment consisted of a brick wall maze with six junctions. There were 16 landmarks in the maze, half of which were on the correct path and half on incorrect paths. Results showed that both groups could learn each route to criterion (two successful completions of a route without error). During the learning phase, the WS group produced more errors than the TD group and took longer to reach criterion. This was predominantly due to the large number of perseverative errors (i.e., errors that were made at the same choice point on consecutive learning trials) made by the WS group relative to the TD children. We suggest that this reflects a difficulty in inhibiting erroneous responses in WS. During the test phase, the TD group showed stronger recall of landmarks adjacent to junctions (more useful landmarks) than of landmarks along path sections (less useful landmarks) independent of each individual's level of nonverbal ability. This pattern was also evident in the WS group but was related to level of nonverbal maturation; the differentiation between recall of junction and path landmarks increased as nonverbal ability increased across WS participants. Overall, the results demonstrate that individuals with WS can learn a route but that the development of this ability is atypical.  相似文献

Spirituality plays an important role in cancer coping among African Americans. The purpose of this study was to report on the initial psychometric properties of instruments specific to the cancer context, assessing the role of spirituality in coping. Items were developed based on a theoretical model of spirituality and qualitative patient interviews. The instruments reflected connections to self, others, God, and the world. One hundred African American cancer survivors completed the instruments by telephone. The instruments showed adequate internal reliability, mixed convergent validity, discriminant validity, and interpretable factor structures.  相似文献

Although relevant nomothetically-based personality literature has made great advances in recent years correlating traits to measures of procrastination, little is known about the specific irrational beliefs of procrastinators, especially when they are actively avoiding tasks or situations. Based on theories from Rational Emotive Behavior Therapy (REBT), it was hypothesized that compared to non-procrastinators, college student academic procrastinators would show greater self depreciation, greater other depreciation, greater life condition depreciation, and a lower frustration tolerance. Academic procrastination was operationally defined by quartile distributions on two self- report measures and three classroom-based assignments. Procrastinators and non-procrastinating students were given instructions to write approximately 500 words about their thoughts and feelings while they were in the process of actively putting off a specific, real event. While actually procrastinating, students logged on to a web site and made text entries describing what was going through their minds. Data were analyzed with the Psychiatric Content and Diagnosis Program Version 3 (PCAD 3; Gottschalk and Bechtel in Psychiatric content and diagnosis: the PCAD 3. GB Software, Brighton, MI, 2007). Procrastinators and non-procrastinators differed on relevant PCAD scales, supporting the hypotheses derived from REBT theory. Treatment implications and directions for future research are discussed.  相似文献

In Germany, Stober et al. (1999, 2001) presented evidence for the validity of the SDS-17, a new measure of social desirability bias. In the current investigation, three experiments (n = 800) assessed the SDS-17’s validity in the US environment. In all conditions SDS-17 scores correlated highly with Marlowe–Crowne scores. In Study 1, a group administration of a paper and pencil booklet, SDS-17 scores of 327 college students were higher under Fake Good than Standard conditions, and both were higher than scores in the Honest condition. Study 2, an online survey of a demographically diverse adult sample (n = 257), showed that the increase in SDS-17 scores under Fake Good conditions occurs also in a Web survey and that SDS-17 scores were unrelated to one’s demographic profile. Study 3, a group administration to 216 college students, revealed again that scores under Fake Good were higher than those under Standard administration and that SDS-17 scores correlated more highly with the Impression Management than with the Self-Deception subscales of the BIDR. The SDS-17 appeared valid for the US environment as a measure of socially desirable responding. The evidence, however, encourages its further assessment as an index of social desirability bias per se.  相似文献
