Offender interviewing in custodial settings: Understanding validity,value and veracity issues

The purpose of this scoping literature review was to identify trends regarding validity, value and veracity issues when conducting (qualitative) interviews with offenders in custodial settings. We selected for review works from electronic databases in SAGE, Springer, and Taylor and Francis by using e-journals, Google Scholar and the behavioural science database, PsycINFO. The inclusion criteria for our studies were based on whether sources addressed offender interviewing as a wellspring of information, but excluded those that focused solely on the acquisition of clinical information (at the expense of focusing on validity, value and veracity issues). We utilised the content analysis approach to identify themes/ patterns in the research findings. Key findings suggest that offenders with impression management motivations deceive and manipulate in their research interview presentations. When gathering data from inmates in custodial care settings, best practice includes cross-checking offender interview data against other sources of evidence and taking into account the context in which they are serving their sentences.     

The role of task difficulty in the control of dynamic balance in children and adults

Although several studies have explored the development of balance control in children, few have addressed the influence of task difficulty on balance control under dynamic and ecologically valid conditions. In this study, reaching tasks in three directions to two distances enabled the examination of balance control in the context of graded task difficulty. Balance control was measured in younger (6 years) and older (10-11 years) children and adults using center of pressure (COP) measures (initial position, excursion, and amplitude) and reach distance. Measures of the initial position of the COP and the excursion of the COP revealed no age-related differences in balance control. Furthermore, balance control, measured by the amplitude of COP movement over the course of the reaching tasks, indicated no differences between the age groups for the least difficult and most difficult tasks. For tasks of moderate difficulty, however, older children displayed levels of balance control similar to younger children for some tasks and higher levels of balance control, similar to adults, for others. This study suggests that (1) process-based measures of balance control are more sensitive in detecting age-related differences, and (2) balance control depends upon both age and the difficulty of the task being performed.
