The structure of the Beck Hopelessness Scale: A confirmatory factor analysis in UK students

The aim of this paper was to confirm the factor structure of the 20-item Beck Hopelessness Scale in a non-clinical population. Previous research has highlighted a lack of clarity in its construct validity with regards to this population.Based on previous factor analytic findings from both clinical and non-clinical studies, 13 separate confirmatory factor models were specified and estimated using LISREL 8.72 to test the one, two and three-factor models.Psychology and medical students at Queen’s University, Belfast (n = 581) completed both the BHS and the Beck Depression Inventory (BDI).All models showed reasonable fit, but only one, a four-item single-factor model demonstrated a non-significant chi-squared statistic. These four items can be used to derive a Short-Form BHS (SBHS) in which increasing scores (0-4) corresponded with increasing scores in the BDI. The four items were also drawn from all three of Beck’s proposed triad, and included both positively and negatively scored items.This study in a UK undergraduate non-clinical population suggests that the BHS best measures a one-factor model of hopelessness. It appears that a shorter four-item scale can also measure this one-factor model.     

Judgments about forces in described interactions between objects

In 4 experiments, participants made judgments about forces exerted and resistances put up by objects involved in described interactions. Two competing hypotheses were tested: (1) that judgments are derived from the same knowledge base that is thought to be the source of perceptual impressions of forces that occur with visual stimuli, and (2) that judgments are generated using simple models or heuristics for deriving force judgments from kinematic information. The results show some similarities with perceptual impression research, particularly that an active object is judged to exert more force on an inactive object than the latter exerts on the former. However, most of the available kinematic information had little or no effect on judgment, supporting the hypothesis that force judgments are generated according to simple rules. Presentation of information about damage to the objects resulted in use of all available kinds of information; this could reflect greater imageability of damage information than kinematic information.     

Reality monitoring in patients with body dysmorphic disorder

Patients with body dysmorphic disorder (BDD) typically have very poor insight into their disorder. Their conviction in their ugliness is often of delusional intensity. Reality monitoring is the ability to distinguish in memory between things that one has imagined and things that one has perceived. Deficits in reality monitoring have been associated with the development of other delusional beliefs. Therefore, in the present study we investigated whether individuals with BDD (n = 20) demonstrate impairments in reality monitoring relative to individuals with obsessive-compulsive disorder (OCD; n = 20) and healthy controls (n = 20). This hypothesized impairment might predispose people with BDD to confuse memories of how they imagine themselves to appear (i.e., ugly) with memories of how they actually appear (i.e., normal). All participants completed a memory task assessing reality-monitoring ability for verbal stimuli. The BDD patients did not exhibit a reality-monitoring deficit despite elevated levels of focal delusionality. The results suggest that impairments in reality monitoring do not contribute to the development or maintenance of appearance-related beliefs in BDD.     

Integrating complementary and alternative therapies into psychological practice: A qualitative analysis

Although complementary and alternative therapies (CATs) are utilised widely for treating psychological disorders, little research has examined psychologists' beliefs about integrating CAT into psychological practice. Six practicing psychologists and six psychology students were interviewed about their CAT integration beliefs, in particular integrating CAT into clinical practice via recommending CATs, offering referrals to CAT practitioners, or undertaking training to utilise CATs within psychological practice. Guided broadly from a theory of planned behaviour perspective, participants raised a number of costs and benefits, discussed referent groups who would influence their decisions, and suggested motivators and barriers for integration. A number of additional themes were raised, including risks, such as the possibility of litigation and the need for clear Society guidelines, as most participants were unclear about what constitutes appropriate practice. Identifying these themes serves as an important initial step to informing discussion and policy for this emerging practice issue within psychology.     

An Examination of the Psychologists' Attitudes Towards Complementary and Alternative Therapies Scale Within a Practitioner Sample

This study assessed the validity of a scale measuring psychologists' attitudes towards complementary and alternative therapies and compared the attitudes of psychologists with a previous sample of psychology students. The scale, derived from existing measures for medical professionals and previously tested on a sample of psychology students, was completed by practising psychologists (N = 122). The data were factor analysed, and three correlated subscales were identified, assessing the perceived importance of knowledge about available therapies, attitudes towards integration with psychological practice, and concerns about associated risks of use. This structure was similar, but not identical, to that found in a previous sample of psychology students; however, psychologists expressed more concern for risks associated with integration and were less likely to hold a positive attitude towards integration. This scale will be useful in gauging changes in psychologists' attitudes towards integrative practice over time.     

Embodied cognition and skilled health behaviour

The present research examines health persuasion from an embodied cognition perspective by proposing that engaging the motor system during presentation of a health message will lead individuals to become more skilled at performing the prescribed behaviour. Participants watched a video on the importance of flossing while either imaging themselves flossing or imaging themselves flossing while minimally engaging the motor system (i.e. touching a piece of floss). Females (but not males) who touched an individual floss while watching the video demonstrated better flossing skills 1 week later. Over time, participants (both males and females) who engaged the motor system also developed more accessible attitudes and had a stronger relationship between their perceived flossing efficacy and actual flossing skill. Implications for the theories of embodied cognition and health interventions are discussed.     

Factor analysis of the Iowa family interaction rating scales

Observational coding systems are uniquely suited for investigating interactional processes in couples and families, but their validity in diverse populations is unknown. We addressed this issue by applying factor analysis to interactional data collected from couples in low-income neighborhoods and coded with the widely used Iowa Family Interaction Rating Scales (IFIRS). Our sample of 414 low-income, ethnically diverse newlywed couples each provided 24-min samples of problem-solving and social support behavior. Interrater reliabilities were strong, and the resultant factors--reflecting positive, negative, and effective communication--were very similar to those obtained with White middle-class samples. Additionally, couples were more negative, less positive, and less effective in problem-solving conversations than in socially supportive conversations, further supporting the validity of the IFIRS in this population. We conclude by discussing the strengths and shortcomings of the IFIRS when used in a low-income, ethnically diverse population.     

Long-term Outcomes of Children and Youth accessing Residential or Intensive Home-based Treatment: Three year follow up

In this study the long-terms outcomes of children and youth with severe mental health problems receiving residential treatment (RT) or an intensive home-based treatment (IHT) were reported. RT is 24-hour mental health intervention in a highly supervised and structured group living setting where individualized and related therapies are provided. Youths attend a day school within the residential environment. IHT developed as an alternative to residential treatment for youth and comprises the same therapeutic interventions provided in the home as opposed to the residential setting. Youths attend their regular school which could be within a specialized setting, such as a day school. At discharge, there were statistically and clinically significant improvements in psychosocial functioning for children and youth in RT and IHT. There were also statistically significant improvements in scores on symptom severity from admission to 12 to 18 months post-discharge, and these improvements were maintained at 36 to 40 months post-discharge. Differences in demographic data between the two groups suggest that the programs may serve two different populations, and that both programs are important components of a comprehensive mental health plan for children and youth.     

Using stimulus control procedures to teach indoor rock climbing to children with autism

The present study evaluated an intervention package for teaching route following to two children with autism at an indoor rock‐climbing gym. The intervention consisted of multiple within‐stimulus fading procedures in combination with errorless learning procedures, positive reinforcement, an error correction procedure, and conditional discrimination training technologies. The results demonstrated that both participants learned to climb at least 10 ft/3 m on specified routes. Furthermore, both participants learned to climb an entire 22‐ft/6.7‐m wall for at least one of three different routes without any errors in a regular rock‐climbing gym setting. The acquisition of this skill provides children with autism with an additional option for leisure participation with others. Copyright © 2010 John Wiley & Sons, Ltd.     

Toddlers use speech disfluencies to predict speakers' referential intentions

The ability to infer the referential intentions of speakers is a crucial part of learning a language. Previous research has uncovered various contextual and social cues that children may use to do this. Here we provide the first evidence that children also use speech disfluencies to infer speaker intention. Disfluencies (e.g. filled pauses 'uh' and 'um') occur in predictable locations, such as before infrequent or discourse-new words. We conducted an eye-tracking study to investigate whether young children can make use of this distributional information in order to predict a speaker's intended referent. Our results reveal that young children (ages 2;4 to 2;8) reliably attend to speech disfluencies early in lexical development and are able to use disfluencies in online comprehension to infer speaker intention in advance of object labeling. Our results from two groups of younger children (ages 1;8 to 2;2 and 1;4 to 1;8) suggest that this ability emerges around age 2.
