Welcome to The International Hypnosis Research Institute Web site. Our intention is to support and promote the further worldwide integration of comprehensive evidence-based research and clinical hypnotherapy with mainstream mental health, medicine, and coaching. We do so by disseminating, supporting, and conducting research, providing professional level education, advocating increased level of practitioner competency, and supporting the viability and success of clinical practitioners. Although currently over 80% of our membership is comprised of mental health practitioners, we fully recognize the role, support, involvement, and needs of those in the medical and coaching fields.

Temporal relationship between change in cognition and change in functioning in schizophrenia.

Most research establishing the relationship between cognition and functioning in schizophrenia has been conducted cross-sectionally, leaving unanswered the question of whether there is a predictive relationship between temporal change in cognition and temporal change in functioning. In the present study, we used longitudinal mixed models to examine the relationship between change in cognition and change in Quality of Life (QLS), as measured over three time-points spanning a 12-month period, for 151 schizophrenia outpatients participating in work therapy with or without cognitive remediation. Memory and executive function changes were significant predictors of improved QLS total. Whereas the relationship between memory and QLS total was in the expected direction, with improvements in memory associated with improvements in QLS, the relationship between executive function and QLS was negative, with QLS improvements associated with declines in executive function. Similar patterns were found for individual QLS domains. Finally, there were positive cross-sectional relationships between QLS and hours worked as well as gender (female gender associated with better QLS). Lag models supported these results. Differences between these findings and previous studies are discussed along with functional assessment issues and the potential moderators of the relationship between cognitive change and functioning.

BACKGROUND: Interrogative suggestibility and compliance are important psychological vulnerabilities during interrogation. The aim of the study was to investigate the relationship of suggestibility and compliance with childhood and current symptoms of attention deficit hyperactivity disorder (ADHD). Compliance has not been studied previously in relation to ADHD. A further aim was to investigate the relationship between ADHD and the reporting of having made a false confession to the police. METHOD: The participants were 90 male prisoners, all of whom had completed the Gudjonsson Suggestibility and Compliance Scales (GSS and GCS) within 10 days of admission to the prison. Childhood ADHD symptoms were screened by the Wender Utah Rating Scale (WURS) and current adult symptoms by the DSM-IV Checklist criteria for ADHD. RESULTS: Half of the prisoners (50%) were found on screening to meet criteria for ADHD in childhood and, of those, over half (60%) were either fully symptomatic or in partial remission of their symptoms. ADHD symptoms were found to be significantly associated with compliance, but not with suggestibility. The relationship with compliance was stronger (effect size) in relation to current than childhood symptoms. The ADHD symptomatic groups were significantly more likely to claim that they had made a false confession to the police in the past. CONCLUSIONS: The findings raise important questions about the potential vulnerability of adults with ADHD symptoms in terms of their ability to cope with interrogation.
