A therapist-assisted cognitive behavior therapy internet intervention for posttraumatic stress disorder: Pre-, post- and 3-month follow-up results from an open trial

This study was an open trial evaluation of a 10-week therapist-assisted cognitive behavior therapy (CBT) internet intervention (PTSD Online) undertaken with people with a primary clinical diagnosis of posttraumatic stress disorder (PTSD) (n=22) at pre-assessment. Participants were re-assessed at post-assessment and 3-month follow-up. Significant improvements on PTSD severity ratings and related PTSD symptomatology were observed at post-assessment and maintained at 3-month follow-up. At post-assessment, 69.2% of the sample showed clinically significant improvement and 77% of the sample at follow-up assessment. Non-significant, yet improved, change was observed on all other general psychological measures. Overall, treatment satisfaction was good (69%), participant therapeutic alliance ratings were high (87.5%), and the average total therapist time required was 194.5 min. PTSD Online appears to be an efficacious treatment option for people with PTSD that can be provided entirely remotely, with far less therapist time than traditional face-to-face treatment, and without compromising therapeutic alliance.

Internet-based treatment for panic disorder: does frequency of therapist contact make a difference?

Internet‐based interventions with therapist support have proven effective for treating a range of mental health conditions. This study examined whether frequency of therapist contact affected treatment outcomes. Fifty‐seven people with panic disorder (including 32 with agoraphobia) were randomly allocated to an 8‐week Internet‐based cognitive behavioural treatment intervention (Panic Online) with either frequent (three e‐mails per week) or infrequent (one e‐mail per week) support from a psychologist. Posttreatment, intention‐to‐treat analyses revealed that both treatments were effective at improving panic disorder and agoraphobia severity ratings, panic‐related cognitions, negative affect, and psychological and physical quality of life domains, with no differences between conditions. High end‐state functioning was achieved by 28.6% of the frequent and infrequent participants, respectively. Therapist alliance, treatment credibility, and satisfaction also did not differ between groups, despite significantly greater therapist time invested in the frequent contact condition. The results provide evidence that the effectiveness of Internet‐based mental health interventions may be independent of the frequency of therapist support and may, therefore, be more cost‐effective than previously reported.

Therapist-Assisted, Internet-Based Treatment for Panic Disorder: Can General Practitioners Achieve Comparable Patient Outcomes to Psychologists?

Background Mental illness is an escalating concern worldwide. The management of disorders such as anxiety and depression largely falls to family doctors or general practitioners (GPs). However, GPs are often too time constrained and may lack the necessary training to adequately manage the needs of such patients. Evidence-based Internet interventions represent a potentially valuable resource to reduce the burden of care and the cost of managing mental health disorders within primary care settings and, at the same time, improve patient outcomes. Objective The present study sought to extend the efficacy of a therapist-assisted Internet treatment program for panic disorder, Panic Online, by determining whether comparable outcomes could be achieved and maintained when Panic Online was supported by either GPs or psychologists. Methods Via a natural groups design, 96 people with a primary diagnosis of panic disorder (with or without agoraphobia) completed the Panic Online program over 12 weeks with the therapeutic assistance of their GP (n = 53), who had received specialist training in cognitive behavioral therapy, or a clinical psychologist (n = 43). Participants completed a clinical diagnostic telephone interview, conducted by a psychologist, and a set of online questionnaires to assess panic-related symptoms at three time periods (pretreatment, posttreatment, and 6 month follow-up). Results Both treatments led to clinically significant improvements on measures of panic and panic-related symptomatology from pretreatment to posttreatment. Both groups were shown to significantly improve over time. Improvements for both groups were maintained at follow-up; however, the groups did differ significantly on two quality of life domains: physical (F1,82 = 9.13, P = .00) and environmental (F1,82 = 4.41, P = .04). The attrition rate was significantly higher among those being treated by their GP (χ 2 1 = 4.40, P = .02, N = 96). Conclusions This study provides evidence that Internet-based interventions are an effective adjunct to existing mental health care systems. Consequently, this may facilitate and enhance the delivery of evidence-based mental health treatments to increasingly large segments of the population via primary care systems and through suitably trained health professionals.

A Therapist‐Assisted Internet‐Based CBT Intervention for Posttraumatic Stress Disorder: Preliminary Results

Posttraumatic stress disorder (PTSD) is a debilitating mental health condition frequently associated with psychiatric comorbidity and diminished quality of life, and it typically follows a chronic, often lifelong, course. Previous research has shown that trauma‐related psychopathology (but not necessarily clinical PTSD) can be effectively treated via the Internet. This study is the first of its kind to report on the online treatment of patients with a Diagnostic and Statistical Manual of Mental Disorders (fourth edition) clinical diagnosis of PTSD with therapist support by e‐mail only. Preliminary findings are presented of an open trial involving a 10‐week Internet‐based therapist‐assisted cognitive behavioural treatment for PTSD (PTSD Online). Pre and posttreatment measures of PTSD and related symptomatology were compared for 16 participants with a variety of trauma experiences. Participants showed clinically significant reductions in PTSD severity and symptomatology, moderate tolerance of the program content, and high therapeutic alliance ratings. No significant change was found on measures of more general psychological symptoms. The results suggest that PTSD Online appears to be an effective and accessible clinical treatment for people with a confirmed PTSD diagnosis.

An evaluation of ‘Reach Out Central’: an online gaming program for supporting the mental health of young people

The objective of this study was to conduct an evaluation of Reach Out Central (ROC), an online gaming program designed to support the mental health of people aged 16-25. The evaluation sought to determine the benefit of playing ROC on alcohol use, use of coping strategies, psychological distress, resilience and satisfaction with life. Changes in mental health literacy, mental health stigma and willingness to seek help and program satisfaction were also investigated. A single group (N = 266) quasi-experimental repeated measures (pre-, post-program, 2-month follow-up) design was employed. The results demonstrated positive improvements across all outcome measures for females; however, a non-significant worsening effect was observed for males on seeking support, avoidance and resilience. Improvements for both genders were observed on mental health literacy and help-seeking. However, literacy levels and help-seeking were significantly higher, and stigma significantly lower for females. Program satisfaction ratings were high irrespective of gender. Although some inconsistencies between genders were noted, ROC appears to enhance protective factors for the prevention or early intervention of mental health disorders. The results of this study need to be viewed with its limitations in mind, specifically, the use of an open trial methodology and the small number of male participants.

An Investigation of Porphyrinuria in Australian Children with Autism

Two recent studies, from France (Nataf et al., 2006) and the United States (Geier & Geier, 2007), identified atypical urinary porphyrin profiles in children with an autism spectrum disorder (ASD). These profiles serve as an indirect measure of environmental toxicity generally, and mercury (Hg) toxicity specifically, with the latter being a variable proposed as a causal mechanism of ASD (Bernard et al., 2001; Mutter et al., 2005). To examine whether this phenomenon occurred in a sample of Australian children with ASD, an analysis of urinary porphyrin profiles was conducted. A consistent trend in abnormal porphyrin levels was evidenced when data was compared with those previously reported in the literature. The results are suggestive of environmental toxic exposure impairing heme synthesis. Three independent studies from three continents have now demonstrated that porphyrinuria is concomitant with ASD, and that Hg may be a likely xenobiotic to produce porphyrin profiles of this nature.

Content and functionality of alcohol and other drug websites: Results of an online survey

Background There is a growing trend for individuals to seek health information from online sources. Alcohol and other drug (AOD) use is a significant health problem worldwide, but access and use of AOD websites is poorly understood. Objective To investigate content and functionality preferences for AOD and other health websites. Methods An anonymous online survey examined general Internet and AOD-specific usage and search behaviors, valued features of AOD and health-related websites (general and interactive website features), indicators of website trustworthiness, valued AOD website tools or functions, and treatment modality preferences. Results Surveys were obtained from 1214 drug (n = 766) and alcohol website users (n = 448) (mean age 26.2 years, range 16-70). There were no significant differences between alcohol and drug groups on demographic variables, Internet usage, indicators of website trustworthiness, or on preferences for AOD website functionality. A robust website design/navigation, open access, and validated content provision were highly valued by both groups. While attractiveness and pictures or graphics were also valued, high-cost features (videos, animations, games) were minority preferences. Almost half of respondents in both groups were unable to readily access the information they sought. Alcohol website users placed greater importance on several AOD website tools and functions than did those accessing other drug websites: online screening tools (χ²2 = 15.8, P < .001, n = 985); prevention programs (χ²2 = 27.5, P < .001, n = 981); tracking functions (χ²2 = 11.5, P = .003, n = 983); self help treatment programs (χ²2 = 8.3, P = .02, n = 984); downloadable fact sheets for friends (χ²2 = 11.6, P = .003, n = 981); or family (χ²2 = 12.7, P = .002, n = 983). The most preferred online treatment option for both the user groups was an Internet site with email therapist support. Explorations of demographic differences were also performed. While gender did not affect survey responses, younger respondents were more likely to value interactive and social networking features, whereas downloading of credible information was most highly valued by older respondents. Conclusions Significant deficiencies in the provision of accessible information on AOD websites were identified, an important problem since information seeking was the most common reason for accessing these websites, and, therefore, may be a key avenue for engaging website users in behaviour change. The few differences between AOD website users suggested that both types of websites may have similar features, although alcohol website users may more readily be engaged in screening, prevention and self-help programs, tracking change, and may value fact sheets more highly. While the sociodemographic differences require replication and clarification, these differences support the notion that the design and features of AOD websites should target specific audiences to have maximal impact.

Ancestry of Pink Disease (Infantile Acrodynia) Identified as a Risk Factor for Autism Spectrum Disorders

Pink disease (infantile acrodynia) was especially prevalent in the first half of the 20th century. Primarily attributed to exposure to mercury (Hg) commonly found in teething powders, the condition was developed by approximately 1 in 500 exposed children. The differential risk factor was identified as an idiosyncratic sensitivity to Hg. Autism spectrum disorders (ASD) have also been postulated to be produced by Hg. Analogous to the pink disease experience, Hg exposure is widespread yet only a fraction of exposed children develop an ASD, suggesting sensitivity to Hg may also be present in children with an ASD. The objective of this study was to test the hypothesis that individuals with a known hypersensitivity to Hg (pink disease survivors) may be more likely to have descendants with an ASD. Five hundred and twenty-two participants who had previously been diagnosed with pink disease completed a survey on the health outcomes of their descendants. The prevalence rates of ASD and a variety of other clinical conditions diagnosed in childhood (attention deficit hyperactivity disorder, epilepsy, Fragile X syndrome, and Down syndrome) were compared to well-established general population prevalence rates. The results showed the prevalence rate of ASD among the grandchildren of pink disease survivors (1 in 25) to be significantly higher than the comparable general population prevalence rate (1 in 160). The results support the hypothesis that Hg sensitivity may be a heritable/genetic risk factor for ASD.

Laser acupuncture for chronic non-specific low back pain: a controlled clinical trial

Objective The primary aim was to determine if laser acupuncture (LA) is more effective than sham laser in reducing pain and disability in adults with chronic non-specific low back pain. Methods The design was a double blind, two-group parallel randomised controlled trial. The active intervention was an 830 nm (infrared), 10 mW, Ga-Al-As laser diode laser for acupuncture and a sham control. The primary outcome measures were changes in pain (visual analogue scale) and disability (Oswestry Disability Index) at the end of 5–10 treatment sessions. Secondary outcomes were patient global assessment, psychological distress (Depression Anxiety Stress Scale) and subjective wellbeing (Personal Wellbeing Index). Follow up was performed at 6 weeks and 6 months after completion of treatment. Results 100 participants were enrolled and treated in a general practice setting. Per protocol analysis of the primary outcome measures using ANOVA suggested that although there was a significant overall improvement in pain and disability after the course of treatments (p<0.01), there was no significant difference between the intervention and control group in both the primary and most secondary outcome measures. Conclusion This study did not show a specific effect for LA using infrared laser at 0.2 Joules per point for chronic low back pain. The overall intervention appeared effective because of placebo and other factors. As there was some concern about baseline inequality between the groups further research using tighter inclusion criteria should attempt to replicate the result and examine if a dose response may exist.

An Update on Gender Differences in the Characteristics Associated with Problem Gambling: a Systematic Review

Purpose of ReviewIdentifying and understanding gender differences associated with the development, maintenance and consequences of problem gambling has important implications for improving prevention and treatment interventions. The current paper systematically reviews the most recent evidence (2012–2015) examining gender differences in the prevalence of problem gambling and the characteristics associated with problem gambling.Recent FindingsTwenty-nine articles, including treatment-seeking and community representative adult and adolescent samples, were included. Males were typically more likely than females to be either at-risk or problem gamblers, although this finding may be an artefact of other characteristics, such as preferred gambling activity. There was consistent evidence that male problem gambling was associated with impulsivity, substance and alcohol use, while female problem gambling was associated with unemployment, psychological distress and childhood abuse.SummaryThe majority of findings, however, were mixed or limited by the small number of studies, highlighting the need for further gender-sensitive research to improve prevention and intervention approaches.
