Websites as a mode of delivering mental health information: perceptions from the Australian public.

BACKGROUND: Many people with a mental disorder do not access help from mental health services. Internet websites may be a useful tool for disseminating mental health information to those who remain untreated, however little is known about people's perceptions of websites as mental health information sources. The current study examined characteristics that may influence belief in the helpfulness of websites as modes of delivering information about mental health. The study compared belief in the helpfulness websites to two traditional sources (bibliotherapy and health educators). METHODS: A total of 3,998 Australians aged 18 and above were surveyed. Logistic regression was used to explore the factors associated with rating a website, book and health educator as helpful sources of mental health information for a person described as having either depression, depression with suicidal thoughts, early schizophrenia or chronic schizophrenia. Factors investigated were demographics, exposure to mental illness, beliefs about dealing with mental illness alone, and personal and perceived stigmatising attitudes. RESULTS: Considerably more participants rated bibliotherapy and health educators as helpful in comparison to websites. Predictors of rating a website and book as helpful were identical; younger age, belief that it is helpful to deal with mental illness alone and being presented with depression and early schizophrenia vignettes in comparison to chronic schizophrenia. Predictors of rating a health educator as helpful were younger age, less personal stigma and being presented with a depression (without suicidal thoughts) vignette in comparison to chronic schizophrenia. CONCLUSIONS: These findings suggest the need for multiple modes of delivering mental health information. While many people feel that information delivered face-to-face is likely to be helpful, websites and other tools that maintain anonymity may be preferred by those who choose to or find themselves dealing with mental illness alone.

The effect of web based depression interventions on self reported help seeking: randomised controlled trial [ISRCTN77824516].

BACKGROUND: To date, there has been very little work investigating behaviour changes induced by interventions that are designed to increase help seeking. The present paper examines the effects of two Internet depression websites on help seeking. METHODS: 414 individuals with elevated scores on a depression assessment scale were randomly allocated to a depression information website, a cognitive-behavioural skills training website (CBT) or an attention control condition. Reports of help seeking for specific treatments, from specific sources and for categories of treatments were assessed. RESULTS: Relative to the control, the depression information site was associated with decreases in seeking support from friends and family, the use of music and of everyday treatments and no increase in seeking evidence based interventions. The CBT site was associated with the report of help seeking for CBT, massage and exercise. CONCLUSION: Methods to encourage the use of evidence-based treatments need further research to determine whether the assistance sought is evidence based and whether there are unintended effects.

Screening young people for autism with the developmental behavior checklist.

OBJECTIVE: To determine whether a subset of items from the Developmental Behavior Checklist (DBC) could be selected to construct a reliable autism screening tool. METHOD: A 29-item scale-the Developmental Behavior Checklist-Autism Screening Algorithm (DBC-ASA)-was developed by using items from the DBC and evaluated in a sample comprising 180 children who met criteria for autism and 180 controls matched for age, sex, and IQ range. RESULTS: This study found that the DBC-ASA has good validity in discriminating young people (4-18 years) with autism and IQ ranging from normal to severe intellectual disability from others using a cutoff score of 17. CONCLUSION: The DBC-ASA is an effective autism screening questionnaire for at-risk young people, including those with intellectual disability.

Change in cognitive functioning associated with apoE genotype in a community sample of older adults.

The influence of a genetic risk factor, apolipoprotein E (apoE) epsilon4 variant, was assessed in older adults aged 70 to 94 on 3 occasions over 7 years. The results of latent growth curve analyses are reported for individuals genotyped for apoE at the 2nd measurement occasion (n = 601) and for a subsample of individuals without probable or definite dementia during the 1st or 2nd occasion (n = 434). ApoE-epsilon4 status was a significant predictor of level and change in memory performance and change in speed performance in the full sample, and of initial level and change in memory performance in the nondemented subsample. These results support previous findings that apoE-epsilon4 is associated with accelerated memory deterioration in individuals without clinical dementia.
