Functional Gastrointestinal Symptoms in Children with Anxiety Disorders

This study examined the incidence and correlates of functional gastrointestinal symptoms in children with anxiety disorders. Participants were 6–13 year old children diagnosed with one or more anxiety disorders (n?=?54) and non-clinical control children (n?=?51). Telephone diagnostic interviews were performed with parents to determine the presence and absence of anxiety disorders in children. Parents completed a questionnaire that elicited information about their child’s gastrointestinal symptoms associated with functional gastrointestinal disorders in children, as specified by the paediatric Rome criteria (Caplan et al., Journal of Pediatric Gastroenterology & Nutrition, 41, 296–304, 2005a). Parents and children also completed a symptom severity measure of anxiety. As expected, children with anxiety disorders were significantly more likely to have symptoms of functional gastrointestinal disorders (FGID), compared to children without anxiety disorders. That is, 40.7 % of anxious children had symptoms of a FGID compared to 5.9 % of non-anxious control children. Children with anxiety disorders were significantly more likely to have symptoms of functional constipation, and showed a trend for a higher incidence of irritable bowel syndrome symptoms compared to non-anxious control children. Furthermore, higher anxiety symptom severity was characteristic of anxious children with symptoms of FGID, compared to anxious children without FGID symptoms and non-anxious control children. Also, children with anxiety disorders, regardless of FGID symptoms, were more likely to have a biological family member, particularly a parent or grandparent, with a gastrointestinal problem, compared to non-anxious control children. The high incidence of FGID symptoms in children with anxiety disorders warrants further research on whether gastrointestinal symptoms reduce following psychological treatments for childhood anxiety disorders, such as cognitive behavioural therapy.     

Concurrent Validity of the Personality Assessment Inventory Borderline Scales in Patients Seeking Dialectical Behavior Therapy

Drawing on a large, nationally representative sample of young adults (the National Longitudinal Study of Adolescent Health; N = 15,701; M age = 29.10), we evaluated the psychometric properties of the Mini-IPIP, a 20-item inventory designed to concisely assess the 5 factors of personality. The results suggest that the Mini-IPIP has a 5-factor structure; most of the scales have acceptable reliability; all the scales have partial or full metric invariance; and the scales exhibit some degree of criterion validity. However, the absence of scalar invariance for many of the scales suggests caution when comparing personality scores among groups defined by sex or race and ethnicity. We offer practical considerations for researchers interested in using this inventory with this sample, and also suggestions for modification of the Mini-IPIP.     

When's your birthday? The self‐reference effect in retrieval of dates

Material encoded with reference to the self is better remembered. One interpretation of this effect is that the self operates to organise retrieval of memories. We were motivated to find out whether this organisational principle extended to everyday information and for material not explicitly related to the self. Participants generated friends' birthdays from memory and then gave their own birthday. We found that participants were particularly likely to recall birthdays from on or around the date of their own birthday. Thus, memory for birthdays clusters around self‐relevant information, even when there is no specific attempt to recall self‐related material. Birthdays clustered somewhat around the time of testing, important dates in the calendar, and for a close other, but not to the extent of the participants' birthdays. We suggest this is a demonstration of the organisational structure of the self in memory. Copyright © 2010 John Wiley & Sons, Ltd.     

Confirmatory Factor Analysis of Warr,Cook, and Wall's (1979) Job Satisfaction Scale

Warr, Cook, and Wall's Job Satisfaction Scale (JSS) is a widely used measure of job satisfaction in industrial/organisational (I/O) psychology research and practice. However, the factor structure has not been adequately explored, with two‐factor and three‐factor solutions previously proposed. This study tested the factor structure of the JSS using robust analysis methods on data gathered from a convenience sample of 381 (females = 264, males = 116) Australian employees. Confirmatory factor analyses supported a hierarchical three‐factor model of job satisfaction in terms of model adequacy coefficients; however, the three factors were highly correlated, thereby rendering a multifactorial approach to the JSS untenable. The results support the continued use of an overall score of job satisfaction when using this measure in I/O psychology research and practice. Further testing of the structure is recommended within a range of employment sectors, as the assumed multifactorial structure of the JSS common in the literature was not supported by the current study.     

Positive involuntary autobiographical memories: You first have to live them

Involuntary autobiographical memories (IAMs) are typically discussed in the context of negative memories such as trauma ‘flashbacks’. However, IAMs occur frequently in everyday life and are predominantly positive. In spite of this, surprisingly little is known about how such positive IAMs arise. The trauma film paradigm is often used to generate negative IAMs. Recently an equivalent positive film was developed inducing positive IAMs (Davies, Malik, Pictet, Blackwell, & Holmes, 2012). The current study is the first to investigate which variables (emotional reaction to the film; recognition memory of the film; participant characteristics) would best predict the frequency of positive IAMs. Higher levels of positive mood change to the film were significantly associated with the number of positive IAMs recorded in the subsequent week. Results demonstrate the importance of positive emotional reaction at the time of an event for subsequent positive IAMs.     

Acceptability of Psychotherapy, Pharmacotherapy, and Self-Directed Therapies in Australians Living with Chronic Hepatitis C

Despite the prevalence of psychiatric co-morbidity in chronic hepatitis C (CHC), treatment is under-researched. Patient preferences are likely to affect treatment uptake, adherence, and success. Thus, the acceptability of psychological supports was explored. A postal survey of Australian CHC outpatients of the Royal Adelaide Hospital and online survey of Australians living with CHC was conducted, assessing demographic and disease-related variables, psychosocial characteristics, past experience with psychological support, and psychological support acceptability. The final sample of 156 patients (58 % male) had significantly worse depression, anxiety, stress, and social support than norms. The most acceptable support type was individual psychotherapy (83 %), followed by bibliotherapy (61 %), pharmacotherapy (56 %), online therapy (45 %), and group psychotherapy (37 %). The most prominent predictor of support acceptability was satisfaction with past use. While individual psychotherapy acceptability was encouragingly high, potentially less costly modalities including group psychotherapy or online therapy may be hampered by low acceptability, the reasons for which need to be further explored.     

Differential Transfer Benefits of Increased Practice for Constant,Blocked, and Serial Practice Schedules

The effects of practice schedule and amount of practice on the development of the generalized motor program (GMP) and on parameter estimation were investigated. Participants (N = 108) practiced the same relative timing but different absolute durations of a multisegment timing task. Practice schedules (constant, blocked, or serial) were crossed with amounts of practice (low and high). Inclusion of a constant practice condition allowed the authors to investigate the variability of practice prediction. Participants practiced the same proportional durations in a serial or a blocked schedule, which enabled the authors to examine contextual interference. A constant practice schedule enhanced GMP performance when task parameters remained the same, but varied practice schedules were beneficial when task parameters changed. A serial as opposed to a blocked practice schedule was superior when the performance of a task governed by a different GMP was required. Increased practice led to a consolidated task representation that was unavailable for updating.
