Intelligent diagnosing of intellectual disabilities in offenders: food for thought

Research on offenders with intellectual disabilities (IDs) in the criminal justice arena is on the rise, reflected by a growing number of relevant publications each year. However, there is a long recognized methodological problem that hampers the comparability of empirical studies and that raises doubts about the accuracy of prevalence rates, comorbidities, and various correlates and characteristics. In this paper we will argue that the crux of the problem can, on the one hand, be found in the plurality of assessment methods for intelligence and adaptive functioning, which are not all sufficiently reliable and valid. On the other hand, assessment of IQ in criminal justice and mental health-related areas appears to be informed more by practical aspects and needs rather than grounded in a solid theoretical model. Hence, we suggest that the Cattell-Horn-Carroll (CHC) model of intelligence has potential value in this regard, and deserves a closer look. Finally, we will discuss its incorporation into, and possible implications for, criminal justice practice and future study designs.     

Anxiety and Depression in Patients with Amyotrophic Lateral Sclerosis and Their Caregivers

A large number of studies have investigated a variety of psychological aspects in people with Amyotrophic Lateral Sclerosis, but there is still considerable uncertainty concerning the actual morbidity, in particular for anxiety. We aim to evaluate depression levels and anxiety disposition in ALS patients and their caregivers, in comparison to healthy controls. We conducted a cross-sectional comparison between people with ALS, their caregivers and a non-clinical control group in order to evaluate anxiety and depression levels. 40 ALS patients, their caregivers and 40 healthy adult subjects completed the Beck Depression Inventory II (BDI-II) and the State-Trait Anxiety Inventory—Y2 scale (STAI). We compared overall and single item scores in order to find differences between the three groups. BDI-II scores were significantly different between groups. Depression scores were higher for patients than for healthy controls, in both somatic and psychological sub-scales. Caregivers presented higher levels of psychological depression in comparison with healthy controls, and lower scores of somatic depression in comparison to patients. No differences were found in trait anxiety levels comparing the three groups. ALS patients and their caregivers developed more depression related symptomatology than the non-clinical sample. However, susceptibility to anxiety for both patients and caregivers seemed to be at a normal level.     

Which processes are involved in cognitive procedural learning?

Procedural memory is characterised by a relative resistance to pathology, making its assessment of the utmost importance. However, few studies have looked at the cognitive processes involved in cognitive procedural learning. In an initial experiment, we studied the role of different cognitive functions in massed cognitive procedural learning. Our results confirmed the existence of three separate learning phases and, for the first time, demonstrated the involvement of episodic memory and executive functions in the first learning phase. In a second experiment, we studied the effect of distributed learning conditions on the dynamics of procedural learning. This second study confirmed our results but showed that these conditions slow down the process of cognitive procedural learning. Our overall findings call into question the status of functionally autonomous memory system that is currently allotted to procedural memory, and suggest that the role of nonprocedural cognitive components should be taken into account in patient rehabilitation.     

The Simon Effect With Wheel-Rotation Responses

The authors examined clockwise and counterclockwise wheel-rotation responses to high- or low-pitched tones presented in participants' (N = 96, Experiment 1; N = 48, Experiment 2; N = 48, Experiment 3) left and right ears. In Experiment 1, a Simon effect (fastest responding when tone location and direction of wheel turn corresponded) was obtained when participants' hands were at the top or middle of the wheel but not at the bottom. With line bottom hand placement, a Simon effect was induced by instructions emphasizing hand movements but not by instructions emphasizing wheel movements (Experiment 2), and by a visual cursor controlled by the wheel but not one triggered by the response (Experiment 3). The results of the experiments showed that the nature of the task and the instructed action goal influence the direction of the Simon effect.     

Ethnic differences in illness perceptions,self-efficacy and diabetes self-care

This study assessed differences between Europeans, South Asians and Pacific Islanders in illness perceptions, self-efficacy, self-care, metabolic control and retinopathy in diabetes. We also evaluated the role of illness perceptions and self-efficacy in diabetes self-care and metabolic control within each group. A total of 86 Europeans, 86 South Asians, and 87 Pacific Islanders with type-2 diabetes completed self-report measures of illness perceptions, self-efficacy and self-care. Metabolic control and retinopathy data were collected from patient records. Results showed that Pacific Islanders and South Asians held shorter illness timeline perceptions compared to Europeans. Relative to both the other groups, Pacific Islanders also had elevated scores on three illness perceptions subscales: consequences, identity and emotional representations. They had lower medication-specific self-efficacy as well as poorer medication self-care, metabolic control and retinopathy. In all three groups, self-efficacy was fairly consistently related to self-care, but not to metabolic control. Illness perceptions were less consistently related to self-care, but were associated with metabolic control.     

Applying multiple models to predict clinicians’ behavioural intention and objective behaviour when managing children's teeth

This study used multiple theoretical approaches simultaneously to predict an objectively measured clinical behaviour. The six theoretical approaches were: The Theory of Planned Behaviour (TPB), Social Cognitive Theory (SCT), Common Sense Self-Regulation Model (CS-SRM), Operant Learning Theory (OLT), Action Planning (AP) and the Precaution Adoption Process (PAP), with knowledge as an additional predictor. Data on variables from these models were collected by postal survey. Data on the outcome behaviour, the evidence-based practice of placing fissure sealants, was collected from clinical records. Participants were 133 dentists (64% male) in Scotland. Variables found to predict the behaviour were: intention, attitude, perceived behavioural control, risk perception, outcome expectancies, self efficacy, habit, anticipated consequences, experienced consequences and action planning. The TPB, SCT, AP, OLT and PAP significantly predicted behaviour but the CS-SRM did not. A combined (Stepwise) regression model included only intention and action planning. Post hoc analyses showed action planning mediated effect of intention on behaviour. Taking a theory-based approach creates a replicable methodology for identifying factors predictive of clinical behaviour and for the design and choice of interventions to modify practice as new evidence emerges, increasing current options for improving health outcomes through influencing the implementation of best practice.     

Application of the Theory of Planned Behaviour in Behaviour Change Interventions: A Systematic Review

This paper reviews studies explicitly applying the Theory of Planned Behaviour (TPB) to behaviour change interventions. A systematic and multiple search strategy identified 30 papers, describing 24 distinct interventions. Studies were rarely explicit about use of the TPB. The TPB was mainly used to measure process and outcome variables and to predict intention and behaviour, and less commonly to develop the intervention. Behaviour change methods were mostly persuasion and information, with increasing skills, goal setting, and rehearsal of skills used less often. When reported, half of the interventions were effective in changing intention, and two-thirds in changing behaviour, with generally small effect sizes, where calculable. Effectiveness was unrelated to use of the theory to develop interventions. Evidence about mediation of effects by TPB components was sparse. The TPB may have potential for developing behaviour change interventions, but more comprehensive studies are needed that compare the utility of the TPB with other social cognition models and behavioural techniques.     

Integrating Psychopathology and Personality Disorders Conceptualized by the MMPI–2–RF and the MCMI–III: A Structural Validity Study

Twenty Es administered Rorschachs expecting Ss to give high or low total numbers of responses, high or low animal in relation to human percentages, and one or another extreme of select personality characteristics. Additionally, each tested a control S expecting “nothing remarkable.” Results indicated tester-bias and suggested that within each comparison group, one expectancy condition contributed disproportionately more to the bias effect than did the other. Video tapes of 20 sessions were analyzed to see whether a Bandura modeling paradigm could account for the mediation of bias; i.e., whether Es modeled their expectancies for the benefit of their Ss and whether Ss consequently imitated their models. This was not supported.
