Effectiveness of home treatment for elderly people with depression: randomised controlled trial

BACKGROUND There is little evidence available about what service models are effective in the treatment of elderly people with depression. AIMS To test the effectiveness of home treatment for elderly people with depression living independently. METHOD In a randomised controlled trial, 60 out-patients aged over 64 years with major depression were allocated to a home treatment model over a 1-year period or to conventional psychiatric out-patient care. The primary outcome was the level of depressive symptoms after 3 and 12 months. The secondary outcomes were global functioning, subjective quality of life (SQOL), admissions to nursing homes, duration of psychiatric hospital treatments and the cost of care. RESULTS Individuals receiving home treatment had significantly fewer symptoms of depression, better global functioning and a higher SQOL at 3 months and at 12 months. Over 1 year they had fewer admissions to nursing homes, spent less time in psychiatric in-patient care and the cost of care was lower. CONCLUSIONS Home treatment appears an effective and cost-effective service model for elderly people with depression.

Volunteering in the care of people with severe mental illness: a systematic review.

BackgroundMuch of the literature to date concerning public attitudes towards people with severe mental illness (SMI) has focused on negative stereotypes and discriminatory behaviour. However, there also exists a tradition of volunteering with these people, implying a more positive attitude. Groups with positive attitudes and behaviours towards people with SMI have received relatively little attention in research. They merit further attention, as evidence on characteristics and experiences of volunteers may help to promote volunteering. The present paper aims to systematically review the literature reporting characteristics, motivations, experiences, and benefits of volunteers in the care of people with SMI.MethodsIn November 2010, a systematic electronic search was carried out in BNI, CINAHL, Embase, Medline, PsycINFO, Cochrane Registers and Web of Science databases, using a combination of ‘volunteer’, ‘mental health’ and ‘outcome’ search terms. A secondary hand search was performed in relevant psychiatric journals, grey literature and references.Results14 papers met the inclusion criteria for the review, with data on a total of 540 volunteers. The results suggest that volunteers are a mostly female, but otherwise heterogeneous group. Motivations for volunteering are a combination of what they can ‘give’ to others and what they can ‘get’ for themselves. Overall volunteers report positive experiences. The main benefit to persons with a psychiatric illness is the gaining of a companion, who is non-stigmatizing and proactive in increasing their social-community involvement.ConclusionsThe evidence base for volunteers in care of people with SMI is small and inconsistent. However there are potential implications for both current and future volunteering programmes from the data. As the data suggests that there is no ‘typical’ volunteer, volunteering programmes should recruit individuals from a variety of backgrounds. The act of volunteering can not only benefit people with SMI, but also the volunteers. Further research may specify methods of recruiting, training, supervising and using volunteers to maximise the benefit for all involved.

Sinusoidal smooth pursuit eye tracking at different stimulus frequencies: position error and velocity error before catch-up saccades in schizophrenia and in major depressive disorder.

Objective: The aim of the present study was to ascertain the extent of impairment of position error and velocity error processing in eye tracking dysfunction in schizophrenic and depressive patients. Method: A total of 21 schizophrenic and 19 unipolar depressive patients and 21 healthy controls were subjected to an eye tracking test with electro-oculography using horizontal sinusoidal stimuli with frequencies of 0.2–0.7 Hz. Position error and velocity error were measured over a saccade-free range of 200 ms before catch-up saccades at 50 ms intervals. Results: For position error, the schizophrenia patients displayed increased values particularly compared to controls, more rarely compared to depressive patients, depending on the stimulus frequency used. The increase in stimulus frequency did not lead to an increase in position error in any group of subjects over a prolonged period. For velocity error, in contrast, the study groups differed only in a few, isolated pre-saccadic intervals. The increase in stimulus frequency, however, led to an increase in velocity error in the schizophrenia patients over the entire 200 ms interval. The depressive patients did not differ notably from the controls, neither in terms of position error nor velocity error. Conclusions: Eye tracking dysfunction in schizophrenia can be described as follows with regard to position error and velocity error: On the one hand, there is an increased position error tolerance largely independent of stimulus frequency, possibly due to an impairment of processing localization information. On the other hand, velocity processing is more severely impaired by an increase in stimulus frequency.
