Objective: To test the effects of a novel cognitive-behavioral therapy (CBT)-based intervention delivered by a nurse therapist to patients with Parkinson disease (PD) with clinically significant impulse control behaviors (ICB).Methods: This was a randomized controlled trial comparing up to 12 sessions of a CBT-based intervention compared to a waiting list control condition with standard medical care (SMC). A total of 27 patients were randomized to the intervention and 17 to the waiting list. Patients with a Mini-Mental State Examination score of ,24 were excluded. The coprimary outcomes were overall symptom severity and neuropsychiatric disturbances in the patients and carer burden and distress after 6 months. Secondary outcome measures included depression and anxiety, marital satisfaction, and work and social adjustment in patients plus general psychiatric morbidity and marital satisfaction in carers.Results: There was a significant improvement in global symptom severity in the CBT intervention group vs controls, from a mean score consistent with moderate to one of mild illness-related symptoms (x 2 5 16.46, p , 0.001). Neuropsychiatric disturbances also improved significantly (p 5 0.03), as did levels of anxiety and depression and adjustment. Measures of carer burden and distress showed changes in the desired direction in the intervention group but did not change significantly. General psychiatric morbidity did improve significantly in the carers of patients given CBT.Conclusions: This CBT-based intervention is the first to show efficacy in ICB related to PD in terms of patient outcomes. The hoped-for alleviation of carer burden was not observed. The study demonstrates the feasibility and potential benefit of a psychosocial treatment approach for these disturbances at least in the short term, and encourages further larger-scale clinical trials.

A non-diagnostic, dimensional construct of disinhibitory psychopathology may be a useful tool to guide research and inform treatment. The role of dysphoria is suggested as a further important factor in driving some of these problem behaviours. This opens the opportunity for adjunctive psychological approaches in management.

Accelerated mental health nurse training attracts talented graduates, many with a psychology degree. Our study shows that such trainees feel incompatible with the nursing culture. Consequently, professional identification is inhibited, and on qualifying these nurses may choose to develop their careers elsewhere. Nurse educators and mentors should pay greater attention to nurturing a positive professional identity in trainees. Alongside their attainment of knowledge and skills, nursing trainees are moulded by a professional culture and inculcated to norms of beliefs and behaviour. The process of professional identification may be inhibited by accelerated nurse training and an influx of psychology graduates potentially using mental health nursing qualification as a springboard to other career opportunities. This study explored facilitators and barriers to professional identification in newly qualified nurses of accelerated postgraduate training. Qualitative interviews were conducted with 10 nurses who had recently completed a postgraduate diploma in mental health nursing at King's College London. Participants identified more with the mental health field than with the broader profession of nursing. They defined their practice in terms of values rather than skills and found difficulty in articulating a distinct role for mental health nursing. Although participants had found experience in training and as a registered practitioner rewarding, they were concerned that nursing may not fulfil their aspirations. Professional identity is likely to be a major factor in satisfaction and retention of nurses. Training and continuing professional development should promote career advancement within clinical nursing practice.

BackgroundImpulse‐control behaviors (ICBs) are increasingly recognized in Parkinson's disease (PD) as drug‐related effects of dopaminergic mediation that occur in 15% to 35% of patients with PD. The authors describe the design and evaluation of a new, clinician‐rated severity scale for the assessment of syndromal and subsyndromal forms of impulse‐control disorders (ICDs), simple (punding) and complex (hobbyism) repetitive behaviors, and compulsive overuse of medication (dopamine dysregulation syndrome).MethodsThe Parkinson's Impulse‐Control Scale (PICS), the first PD‐specific, semistructured interview to cover the full range of PD‐related ICBs, is described along with initial evidence on its clinimetric properties including interrater reliability, discriminant validity and sensitivity to change. A convenience sample of PD patients with ICBs and those without were administered a semistructured interview (n = 92).ResultsThe scale distinguished between those with and without clinically detected ICBs and between patients with syndromal ICD and subsyndromal ICB (receiver operating characteristic areas under the curve, 92%–95%). Cutoff values were suggested, and substantial agreement was reported on weighted kappa (Κ) values for clinician‐clinician rating of severity (Κ = 0.92). Significant improvements were detected on the scale after a randomized controlled trial of cognitive‐behavioral therapy and medication adjustment (t[22] = 5.47; P < 0.001).ConclusionsThe PICS appears to be a reliable measure of the full range of PD ICBs with good levels of interrater reliability. It may provide a useful measure to assess the severity of ICBs and monitor change in clinical and research settings; although, given the specialized centers used for recruitment of this sample, further psychometric evaluation is required.
