    Input: OBJECTIVE Veterans who served in Operation Enduring Freedom ( OEF ) and Operation Iraqi Freedom ( OIF ) commonly experience alcohol misuse and symptoms of posttraumatic stress disorder ( PTSD ) following their return from deployment to a war zone . We conducted a r and omized clinical trial to evaluate the efficacy of a newly developed , 8-module , self-management web intervention ( VetChange ) based on motivational and cognitive-behavioral principles to reduce alcohol consumption , alcohol-related problems , and PTSD symptoms in returning combat veterans . METHOD Six hundred participants , recruited through targeted Facebook ads , were r and omized to either an Initial Intervention Group ( IIG ; n = 404 ) or a Delayed Intervention Group ( DIG ; n = 196 ) that waited 8 weeks for access to VetChange . Primary outcome measures were Drinks per Drinking Day , Average Weekly Drinks , Percent Heavy Drinking Days , and PTSD symptoms . Intent-to-treat analyses compared changes in outcome measures over time between IIG and DIG as well as within-group changes . RESULTS IIG participants demonstrated greater reductions in drinking ( p < .001 for each measure ) and PTSD symptoms ( p = .009 ) between baseline and end-of-intervention than did DIG participants between baseline and the end of the waiting period . DIG participants showed similar improvements to those in IIG following participation in VetChange .  Alcohol problems were also reduced within each group between baseline and 3-month follow-up . CONCLUSIONS Results indicate that VetChange is effective in reducing drinking and PTSD symptoms in OIF/OEF veterans . Further studies of VetChange are needed to assess web-based recruitment and retention methods and to determine VetChange 's effectiveness in demographic and clinical sub- population s of returning veterans Background Guided self-help interventions for PTSD ( post-traumatic stress disorder ) are a promising tool for the dissemination of contemporary psychological treatment . Objective This study investigated the efficacy of the Chinese version of the My Trauma Recovery ( CMTR ) website . Methods In an urban context , 90 survivors of different trauma types were recruited via Internet advertisements  and allocated to a r and omized controlled trial ( RCT ) with a waiting list control condition . In addition , in a rural context , 93 survivors mainly of the 2008 Sichuan earthquake were recruited in-person for a parallel RCT in which the website intervention was conducted in a counseling center and guided by volunteers . Assessment was completed online on a professional Chinese survey website . The primary outcome measure was the Post-traumatic Diagnostic Scale ( PDS ) ; secondary outcome measures were Symptom Checklist 90-Depression ( SCL-D ) , Trauma Coping Self-Efficacy Scale ( CSE ) , Post-traumatic Cognitive Changes ( PCC ) , and Social Functioning Impairment ( SFI ) question naires adopted from the My Trauma Recovery website . Results For the urban sample , findings indicated a significant group × time interaction in post-traumatic symptom severity ( F 1,88=7.65 , P=.007 ) . CMTR reduced post-traumatic symptoms significantly with high effect size after one month of treatment ( F 1,45=15.13 , Cohen ’s d=0.81 , P<.001 ) and the reduction was sustained over a 3-month follow-up ( F 1,45=17.29 , Cohen ’s d=0.87 , P<.001 ) . In the rural sample , the group × time interaction was also significant in post-traumatic symptom severity ( F 1,91=5.35 , P=.02 ) . Post-traumatic symptoms decreased significantly after treatment ( F 1,48=43.97 , Cohen ’s d=1.34 , P<.001 ) and during the follow-up period ( F 1,48=24.22 , Cohen ’s d=0.99 , P<.001 ) . Additional outcome measures ( post-traumatic cognitive changes , depression ) indicated a range of positive effects , in particular in the urban sample ( group × time interactions : F 1,88=5.32 - 8.37 , all Ps<.03 ) , contributing to the positive evidence for self-help interventions . Differences in the effects in the two RCTs are exploratorily explained by sociodemographic , motivational , and setting feature differences between the two sample s. Conclusions These findings give support for the short-term efficacy of CMTR in the two Chinese population s and contribute to the literature that self-help Web-based programs can be used to provide mental health help for traumatized persons . Trial Registration Australia New Zeal and Clinical Trials Registry ( ANZCTR ) : ACTRN12611000951954 ; https://www.anzctr.org.au/Trial/ Registration /Trial Review .aspx?ACTRN=12611000951954 ( Archived by WebCite at http://www.webcitation.org/6G7WyNODk ) Online therapy offers many advantages over face-to-face therapy . Interapy includes psychoeducation , screening , effect measures , and a protocol -driven treatment via the Internet for people suffering from posttraumatic stress . The present article reports the results of a controlled trial on the Internet-driven treatment of posttraumatic stress and grief in a group of people who manifested mild to relatively severe trauma symptoms . Participants in the treatment condition ( n=69 ) improved significantly more than participants in the waiting-list control condition ( n=32 ) on trauma-related symptoms and general psychopathology . The effect sizes were large . On most subscales , more than 50 % of the treated participants showed reliable change and clinical ly significant improvement , with the highest percentages being found for depression and avoidance Background Posttraumatic stress disorder ( PTSD ) develops in 10 - 20 % of injury patients . We developed a novel , self-guided Internet-based intervention ( called Trauma TIPS ) based on techniques from cognitive behavioral therapy ( CBT ) to prevent the onset of PTSD symptoms . Objective To determine whether Trauma TIPS is effective in preventing the onset of PTSD symptoms in injury patients . Methods Adult , level 1 trauma center patients were r and omly assigned to receive the fully automated Trauma TIPS Internet intervention ( n=151 ) or to receive no early intervention ( n=149 ) .  Trauma TIPS consisted of psychoeducation , in vivo exposure , and stress management techniques . Both groups were free to use care as usual ( non protocol ized talks with hospital staff ) . PTSD symptom severity was assessed at 1 , 3 , 6 , and 12 months post injury with a clinical interview ( Clinician-Administered PTSD Scale ) by blinded trained interviewers and self-report instrument ( Impact of Event Scale — Revised ) . Secondary outcomes were acute anxiety and arousal ( assessed online ) , self-reported depressive and anxiety symptoms ( Hospital Anxiety and Depression Scale ) , and mental health care utilization . Intervention usage was documented . Results The mean number of intervention logins was 1.7 , SD 2.5 , median 1 , interquartile range ( IQR ) 1 - 2 . Thirty-four patients in the intervention group did not log in ( 22.5 % ) , 63 ( 41.7 % ) logged in once , and 54 ( 35.8 % ) logged in multiple times ( mean 3.6 , SD 3.5 , median 3 , IQR 2 - 4 ) . On clinician-assessed and self-reported PTSD symptoms , both the intervention and control group showed a significant decrease over time ( P<.001 ) without significant differences in trend . PTSD at 12 months was diagnosed in 4.7 % of controls and 4.4 % of intervention group patients . There were no group differences on anxiety or depressive symptoms over time . Post hoc analyses using latent growth mixture modeling showed a significant decrease in PTSD symptoms in a subgroup of patients with severe initial symptoms ( n=20 ) ( P<.001 ) . Conclusions Our results do not support the efficacy of the Trauma TIPS Internet-based early intervention in the prevention of PTSD symptoms for an unselected population of injury patients . Moreover , uptake was relatively low since one-fifth of individuals did not log in to the intervention . Future research should therefore focus on innovative strategies to increase intervention usage , for example , adding gameplay , embedding it in a blended care context , and targeting high-risk individuals who are more likely to benefit from the intervention . Trial Registration International St and ard R and omized Controlled Trial Number ( IS RCT N ) : 57754429 ; http://www.controlled-trials.com/IS RCT N57754429 ( Archived by WebCite at http://webcitation.org/6FeJtJJyD ) A total of 117 depressed clients , stratified for severity , completed 8 or 16 sessions of manualized treatment , either cognitive-behavioral psychotherapy ( CB ) or psychodynamic-interpersonal psychotherapy ( PI ) . Each of 5 clinician-investigators treated clients in all 4 treatment conditions . On most measures , CB and PI were equally effective , irrespective of the severity of depression or the duration of treatment . However , there was evidence of some advantage to CB on the Beck Depression Inventory ( Beck , Ward , Mendelson , Mock , & Erbaugh , 1961 ) . There was no evidence that CB 's effects were more rapid than those of PI , nor did the effects of each treatment method vary according to the severity of depression . There was no overall advantage to 16-session treatment over 8-session treatment . However , those presenting with relatively severe depression improved substantially more after 16 than after 8 sessions On-line therapy offers many advantages over face-to-face setting s. Interapy includes psycho-education , screening , effect measures and protocol -driven treatment via the Internet for clients . The present paper reports the results of a controlled trial on the Interapy treatment of posttraumatic stress and grief in students , gaining course credits . The participants in the experimental condition ( n = 13 ) improved significantly than the participants in the waiting-list control condition ( n = 12 ) , on trauma-related symptoms and general psychopathology . The effect sizes were large . Eighty percent of the treated participants showed clinical ly significant improvement after treatment . The possibilities for future research with Interapy , including studies into moderating variables , are discussed BACKGROUND Posttraumatic stress disorder ( PTSD ) is a severe and disabling condition and few receive appropriate care . Internet-based treatment of PTSD shows promise in reducing barriers to care and preliminary evidence suggests it is efficacious in treating symptoms of PTSD . METHODOLOGY Forty-two individuals with a diagnosis of PTSD confirmed by clinician interview completed a r and omized controlled comparison of Internet-based cognitive behavioral therapy ( CBT ) with a waitlist control condition . PRINCIPLE FINDINGS Large pre- to posttreatment effect sizes ( ESs ) were found for the Treatment group on measures of PTSD symptoms , depression , anxiety , and disability . A small between-group ES was found for PTSD symptoms and moderate between-group ESs were found for depression , anxiety , and disability . CONCLUSIONS Results provide preliminary support for Internet-based CBT as an efficacious treatment for individuals with a confirmed primary diagnosis of PTSD 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 clinical ly 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 BACKGROUND Compared to those with depression alone , depressed patients with posttraumatic stress disorder ( PTSD ) experience more severe psychiatric symptomatology and factors that complicate treatment . OBJECTIVE To estimate PTSD prevalence among depressed military veteran primary care patients and compare demographic/illness characteristics of PTSD screen-positive depressed patients ( MDD-PTSD+ ) to those with depression alone ( MDD ) . DESIGN Cross-sectional comparison of MDD patients versus MDD-PTSD+ patients . PARTICIPANTS Six hundred seventy-seven r and omly sample d depressed patients with at least 1 primary care visit in the previous 12 months . Participants composed the baseline sample of a group r and omized trial of  collaborative care for depression in 10 VA primary care practice s in 5 states . MEASUREMENTS The Patient Health Question naire-9 assessed MDD . Probable PTSD was defined as a Primary Care PTSD Screen ≥ 3 . Regression-based techniques compared MDD and MDD-PTSD+ patients on demographic/illness characteristics . RESULTS Thirty-six percent of depressed patients screened positive for PTSD . Adjusting for sociodemographic differences and physical
