Internet-based self-help with therapist feedback and in vivo group exposure for social phobia: A randomized controlled trial.

Sixty-four individuals with social phobia (social anxiety disorder) were assigned to a multimodal cognitive-behavioral treatment package or to a waiting list control group. Treatment consisted of a 9-week, Internet-delivered, self-help program that was combined with 2 group exposure sessions in real life and minimal therapist contact via e-mail. Results were analyzed on an intention-to-treat basis, including all randomized participants. From pre- to posttest, treated participants in contrast to controls showed significant improvement on most measured dimensions (social anxiety scales, general anxiety and depression levels, quality of life). The overall within- and between-groups effect sizes were Cohens d = 0.87 and 0.70, respectively. Treatment gains were maintained at 1-year follow-up. The results from this study support the continued use and development of Internet-distributed, self-help programs for people diagnosed with social phobia.

Excess mortality, causes of death and prognostic factors in anorexia nervosa

BACKGROUND Anorexia nervosa is a mental disorder with high mortality. AIMS To estimate standardised mortality ratios (SMRs) and to investigate potential prognostic factors. METHOD Six thousand and nine women who had in-patient treatment for anorexia nervosa were followed-up retrospectively using Swedish registers. RESULTS The overall SMR for anorexia nervosa was 6.2 (95% CI 5.5-7.0). Anorexia nervosa, psychoactive substance use and suicide had the highest SMR. The SMR was significantly increased for almost all natural and unnatural causes of death. The SMR 20 years or more after the first hospitalisation remained significantly high. Lower mortality was found during the last two decades. Younger age and longer hospital stay at first hospitalisation was associated with better outcome, and psychiatric and somatic comorbidity worsened the outcome. CONCLUSIONS Anorexia nervosa is characterised by high lifetime mortality from both natural and unnatural causes. Assessment and treatment of psychiatric comorbidity, especially alcohol misuse, may be a pathway to better long-term outcome.

Treatment of panic disorder via the Internet: a randomized trial of CBT vs. applied relaxation.

A randomized trial was conducted of two different self-help programs for panic disorder (PD) on the Internet. After confirming the PD-diagnosis with an in-person structured clinical interview for DSM-IV (SCID) interview 22 participants were randomized to either applied relaxation (AR) or a multimodal treatment package based on cognitive behavioral therapy (CBT). Overall, the results suggest that Internet-administered self-help plus minimal therapist contact via e-mail has a significant medium to large effect (Cohens d=0.71 for AR and d=0.42 for CBT). The results from this study generally provide evidence to support the continued use and development of Internet-distributed self-help programs.

Swedish universities Scales of Personality (SSP): construction, internal consistency and normative data

Objective: A thorough revision of the Karolinska Scales of Personality (KSP) was made by reducing the number of items and improving the psychometric quality as concerns face validity, internal consistency and response differentiation. The revised version was labelled The Swedish universities Scales of Personality (SSP) and now include 91 items divided into 13 scales.

SCID II interviews and the SCID Screen questionnaire as diagnostic tools for personality disorders in DSM-III-R

A modified version of the SCID Screen questionnaire covering 103 criteria by means of 124 questions was compared with SCID II interviews in 69 psychiatric patients. The correlation between the number of criteria fulfilled in the SCID II interviews or the questionnaires was 0.84. In the SCID interviews, 54% of the patients had a personality disorder. When the SCID Screen questionnaire was used, 73% had a personality disorder. When the cut‐off level for diagnosis was adjusted, the frequency found by means of the SCID screen questionnaire or the interviews was roughly the same, 58% and 54%, respectively. The overall kappa for agreement between the SCID II interviews and questionnaire with adjusted cut‐off was 0.78.

Guided and unguided self-help for social anxiety disorder : randomised controlled trial

BACKGROUND Internet-delivered self-help programmes with added therapist guidance have shown efficacy in social anxiety disorder, but unguided self-help has been insufficiently studied. AIMS To evaluate the efficacy of guided and unguided self-help for social anxiety disorder. METHOD Participants followed a cognitive-behavioural self-help programme in the form of either pure bibliotherapy or an internet-based treatment with therapist guidance and online group discussions. A subsequent trial was conducted to evaluate treatment specificity. Participants (n = 235) were randomised to one of three conditions in the first trial, or one of four conditions in the second. RESULTS Pure bibliotherapy and the internet-based treatment were better than waiting list on measures of social anxiety, general anxiety, depression and quality of life. The internet-based therapy had the highest effect sizes, but directly comparable effects were noted for bibliotherapy augmented with online group discussions. Gains were well maintained a year later. CONCLUSIONS Unguided self-help through bibliotherapy can produce enduring improvement for individuals with social anxiety disorder.

Prevalence of psychiatric disorders in infertile women and men undergoing in vitro fertilization treatment

BACKGROUND This study was undertaken to determine the prevalence of psychiatric disorders in infertile women and men undergoing in vitro fertilization (IVF) treatment. METHODS Participants were 1090 consecutive women and men, 545 couples, attending a fertility clinic in Sweden during a two-year period. The Primary Care Evaluation of Mental Disorders (PRIME-MD), based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edn (DSM-IV), was used as the diagnostic tool for evaluating mood and anxiety disorders. RESULTS Overall, 862 (79.1%) subjects filled in the PRIME-MD patient questionnaire. Any psychiatric diagnosis was present in 30.8% of females and in 10.2% of males in the study sample. Any mood disorder was present in 26.2% of females and 9.2% of males. Major depression was the most common mood disorder, prevalent in 10.9% of females and 5.1% of males. Any anxiety disorder was encountered in 14.8% of females and 4.9% males. Only 21% of the subjects with a psychiatric disorder according to DSM-IV received some form of treatment. CONCLUSIONS Mood disorders are common in both women and men undergoing IVF treatment. The majority of subjects with a psychiatric disorder were undiagnosed and untreated.

Major depression and posttraumatic stress disorder symptoms following severe burn injury in relation to lifetime psychiatric morbidity

BACKGROUND Psychiatric history has been suggested to have an impact on long-term adjustment in burn survivors. A rigorous, prospective, longitudinal approach was used to study psychiatric history in a population-based burn sample and its impact on symptomatology of depression and posttraumatic stress disorder (PTSD) at a 12-month follow-up. METHODS Seventy-three consecutive patients admitted to the Uppsala Burn Unit were assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition for psychiatric disorders, of whom 64 were also assessed after 12 months. RESULTS Forty-eight patients (66%) presented with at least one lifetime psychiatric diagnosis; major depression (41%), alcohol abuse or dependence (32%), simple phobia (16%), and panic disorder (16%) were most prevalent. At 12-months postburn, 10 patients (16%) met criteria for major depression, 6 (9%) for PTSD, and 11 (17%) for subsyndromal PTSD. Patients with lifetime anxiety disorder and with lifetime psychiatric comorbidity were more likely to be depressed at 12 months, whereas those with lifetime affective disorder, substance use disorder and psychiatric comorbidity were more likely to have symptoms of PTSD. CONCLUSIONS Two-thirds of burn survivors exhibit a history of lifetime psychiatric disorders. Those with a psychiatric history have a higher risk of postburn psychiatric problems.

Sex steroid-related genes and male-to-female transsexualism.

Transsexualism is characterised by lifelong discomfort with the assigned sex and a strong identification with the opposite sex. The cause of transsexualism is unknown, but it has been suggested that an aberration in the early sexual differentiation of various brain structures may be involved. Animal experiments have revealed that the sexual differentiation of the brain is mainly due to an influence of testosterone, acting both via androgen receptors (ARs) and--after aromatase-catalyzed conversion to estradiol--via estrogen receptors (ERs). The present study examined the possible importance of three polymorphisms and their pairwise interactions for the development of male-to-female transsexualism: a CAG repeat sequence in the first exon of the AR gene, a tetra nucleotide repeat polymorphism in intron 4 of the aromatase gene, and a CA repeat polymorphism in intron 5 of the ERbeta gene. Subjects were 29 Caucasian male-to-female transsexuals and 229 healthy male controls. Transsexuals differed from controls with respect to the mean length of the ERbeta repeat polymorphism, but not with respect to the length of the other two studied polymorphisms. However, binary logistic regression analysis revealed significant partial effects for all three polymorphisms, as well as for the interaction between the AR and aromatase gene polymorphisms, on the risk of developing transsexualism. Given the small number of transsexuals in the study, the results should be interpreted with the utmost caution. Further study of the putative role of these and other sex steroid-related genes for the development of transsexualism may, however, be worthwhile.
