No decision‐maker is an Island: integrating expert advice with information acquisition

The present research examined the social context of information acquisition. The main purpose was to examine how decision‐makers' information acquisition processes changed when they were provided access to expert advice. Results indicated that all decision‐makers opted to acquire advice; however, they typically did so only after completing over 75% of their own information search. Decision‐makers agreed more with the advice as task complexity increased, but, in general, searched information in two stages—i.e., a pre‐advice “hypothesis generation” stage and a post‐advice “hypothesis testing” stage. To behave in an adaptive manner, decision‐makers could have used expert advice either to increase their decision accuracy or to reduce their effort expenditure (or both); they chose the former. Implications and further extensions are discussed. Copyright © 2006 John Wiley & Sons, Ltd.     

Silent talker: a new computer‐based system for the analysis of facial cues to deception

This paper presents the development of a computerised, non‐invasive psychological profiling system, ‘Silent Talker’, for the analysis of non‐verbal behaviour. Nonverbal signals hold rich information about mental, behavioural and/or physical states. Previous attempts to extract individual signals and to classify an overall behaviour have been time‐consuming, costly, biased, error‐prone and complex. Silent Talker overcomes these problems by the use of Artificial Neural Networks. The testing and validation of the system was undertaken by detecting processes associated with ‘deception’ and ‘truth’. In a simulated theft scenario thirty‐nine participants ‘stole’ (or didn't) money, and were interviewed about its location. Silent Talker was able to detect different behaviour patterns indicative of ‘deception’ and ‘truth’ significantly above chance. For example, when 15 European men had no prior knowledge of the exact questions, 74% of individual responses ( p < 0.001) and 80% ( p = 0.035) of interviews were classified correctly.

Calculating savings to the nation from counselling services: Methodological challenges

The research endeavoured to develop and pilot a system to demonstrate savings to the nation resulting from counselling provided by a national voluntary agency. This paper demonstrates the methodological challenges encountered. A questionnaire was developed, focused on four broad dimensions of clients’ lives: Employment & Income, Health, Personal & Social, and Children. The questionnaire was piloted by eight counselling centres, and applied pre‐ and post‐intervention. It proved not always possible to attribute clear savings within the dimensions measured. Direct health‐related costs and sick days off work were relatively straightforward. However, for less tangible factors, e.g. personal and social, and children, it was not possible to attribute direct financial amounts to any improvements. The pilot, therefore, attributed savings where possible. Attrition was a major difficulty, with 976 pre‐intervention questionnaires reducing to only 159 post‐intervention. This paper indicates the challenges of estimating savings to the nation from counselling interventions, and illustrates a flexible flowchart which allows savings and costs to be attributed as and when available. Although no final calculations of savings to the nation are included, it is believed that the learning from the methodological challenges encountered should be useful to other services wishing to assess the financial costs and savings of psychological therapies and counselling.     

Couples’ Attributions for Work Function Changes in Prodromal Huntington Disease

People who have tested positive for the expanded Huntington disease (HD) gene who are not yet diagnosed (pre-HD) and their companions report subtle changes in ability of people with pre-HD to do their jobs. However, it is not known whether they attribute these changes to HD. Semi-structured telephone interviews were analyzed from seven persons with pre-HD at different estimated points from diagnosis and six companions. Data were analyzed using qualitative analysis methods. Participants made attributions related to health, work, and temperament. Only one participant attributed a change to HD. The process of forming attributions was demonstrated through symptom monitoring and comparison of participants with pre-HD to others with and without HD. Participants also expressed uncertainty regarding how to make attributions. Attributions influence coping procedures, including whether to seek and accept medical treatment. In persons with prodromal HD the relationship between attributions and use of coping strategies for symptoms that interfere with job functioning is unknown.     

Advancing measurement of work and family domain boundary characteristics

Recent research offers promising theoretical frameworks for thinking about the work–family interface in terms of the boundaries individuals develop around work and family. However, measures for important constructs proposed by these theories are needed. Using two independent samples, we report on the refinement of existing boundary flexibility measures. Additionally, inter-domain transitions are introduced as a theoretically sound conceptualization of the frequency with which the work and family domains come in contact. Results from Study 1 further support the existence of two flexibility factors, willingness and ability, for the work and family domains, respectively. Results from Study 2 provide evidence for the nomological network surrounding the flexibility and inter-domain transitions measures in relation to role centrality, perceptions of domain blurring, and family-supportive organizational perceptions. Also, as hypothesized, boundary flexibility predicted inter-domain transitions, and inter-domain transitions predicted work–family conflict, with additional support for several hypothesized mediated effects between these constructs.     

Habitual starvation and provocative behaviors: Two potential routes to extreme suicidal behavior in anorexia nervosa

Anorexia nervosa (AN) is perhaps the most lethal mental disorder, in part due to starvation-related health problems, but especially because of high suicide rates. One potential reason for high suicide rates in AN may be that those affected face pain and provocation on many fronts, which may in turn reduce their fear of pain and thereby increase risk for death by suicide. The purpose of the following studies was to explore whether repetitive exposure to painful and destructive behaviors such as vomiting, laxative use, and non-suicidal self-injury (NSSI) was a mechanism that linked AN-binge-purging (ANBP) subtype, as opposed to AN-restricting subtype (ANR), to extreme suicidal behavior. Study 1 utilized a sample of 787 individuals diagnosed with one or the other subtype of AN, and structural equation modeling results supported provocative behaviors as a mechanism linking ANBP to suicidal behavior. A second, unexpected mechanism emerged linking ANR to suicidal behavior via restricting. Study 2, which used a sample of 249 AN patients, replicated these findings, including the second mechanism linking ANR to suicide attempts. Two potential routes to suicidal behavior in AN appear to have been identified: one route through repetitive experience with provocative behaviors for ANBP, and a second for exposure to pain through the starvation of restricting in ANR.     

Effects of an indicated cognitive-behavioral depression prevention program are similar for Asian American, Latino, and European American adolescents

The authors tested whether a brief indicated cognitive-behavioral depression prevention program produced similar effects for Asian American, Latino, and European American adolescents (M age = 17.3, SD = 1.6) with elevated depressive symptoms using data from two randomized trials. The first trial involved 37 Asian-American/Pacific Islanders, 32 Latinos, and 98 European Americans and the second trial involved 61 Latinos and 72 European Americans. Reductions in depressive symptoms from pre- to post-intervention and from pre to 6-month follow-up for intervention participants versus assessment-only controls did not differ significantly for the various ethnic groups in either trial, despite sufficient power to detect clinically meaningful differences. These findings suggest that this indicated depression prevention intervention is similarly efficacious for Asian American, Latino and European American adolescents.
