Reviews of the relative efficacy of psychotherapy and combined therapy (psychotherapy with pharmacotherapy) for depression have yielded contradicting conclusions. This may be explained by the clinical heterogeneity of the studies reviewed.

To conduct a meta-analysis with an acceptable level of homogeneity in order to investigate the relative efficacy of psychotherapy and combined therapy in the acute treatment of depression.

A systematic search was performed for RCTs published between 1980 and 2005 comparing psychotherapy and combined therapy in adult psychiatric outpatients with non-psychotic unipolar major depressive disorder. The studies were classified according to the chronicity and severity of the depression. Data were pooled by means of meta-analysis and statistical tests were conducted to measure heterogeneity.

The meta-analysis included seven studies looking at a total of 903 patients. None of the heterogeneity tests established significance. This indicates a lack of evidence for the heterogeneity of the results. The dropout rates did not differ significantly between the two treatment modalities (25% in combined therapy and 24% in psychotherapy, p = 0.77). At treatment termination, the intention-to-treat remission rate for combined therapy (46%) was better than for psychotherapy (34%) (p = 0.0007); Relative Risk 1.32 (95% CI: 1.12–1.56), Odds Ratio 1.59 (95% CI: 1.22–2.09). In moderate depression, the difference between the remission rate for combined therapy and psychotherapy was statistically significant (47% compared to 34% respectively, p = 0.001). This was not the case in mild major depression (42% compared to 37% respectively, p = 0.29). The difference was also statistically significant in chronic major depression (48% compared to 32%, p < 0.001), but not in non-chronic major depression (43% compared to 37%, p = 0.22). On a more specific level, no differences were found in the remission rates for the treatment modalities in mild or moderate non-chronic depression. Combined therapy led to significantly better results than psychotherapy in moderate chronic depression only (48% compared to 32%, p < 0.001).

In the acute treatment of adult psychiatric outpatients with major depressive disorder, patient compliance with combined therapy matches compliance with psychotherapy alone. Combined therapy is more efficacious than psychotherapy alone. However, these results depend on severity and chronicity. Combined therapy outperformed psychotherapy in moderate chronic depression only. No differences were found in mild and moderate non-chronic depression. No data were found for mild chronic depression and for severe depression.

In the past decades, the effects of problem-solving therapy (PST) for depression have been examined in several randomized controlled studies. However, until now no meta-analysis has tried to integrate the results of these studies.

We conducted a systematic literature search and identified 13 randomized studies examining the effects of PST, with a total of 1133 subjects. The quality of studies varied.

The mean standardized effect size was 0.34 in the fixed effects model and 0.83 in the random effects model, with very high heterogeneity. Subgroup analyses indicated significantly lower effects for individual interventions in studies with subjects who met criteria for major depression, studies in which intention-to-treat analyses were conducted instead of completers-only analyses, and studies with pill placebo and care-as-usual control groups. Heterogeneity was high, and the subgroup analyses did not result in clear indications of what caused this high heterogeneity. This indicates that PST has varying effects on depression, and that it is not known to date what determines whether PST has larger of smaller effects.

Although there is no doubt that PST can be an effective treatment for depression, more research is needed to ascertain the conditions and subjects in which these positive effects are realized.

Familial aggregation of major depression might indicate a genetic liability for the disorder. The complete disorder or, alternatively, only some individual symptoms might be inherited. Under the latter condition, an increased frequency of inherited symptoms might consecutively increase the likelihood to reach the threshold for depression in relatives and, thus, might cause the familial aggregation of depression. Up to now, no study investigated the possibility of a relationship between individual depressive symptoms and the familial aggregation of depression.

The familial aggregation of early-onset depression (age-at-onset < 60 years, EOD) but less so of late-onset depression (LOD) has been shown in this sample. To assess the hypothesis of an inheritance of individual depressive symptoms as a possible cause of the familial aggregation of depression, frequencies of symptoms were compared in relatives of depressed patients and of controls using forward logistic regression analyses.

Some individual depressive symptoms showed clustering in relatives of patients with depression, but the pattern of inheritance was inconsistent, i.e. the clustering of symptoms was different between non-depressed and depressed relatives of patients with EOD and LOD, respectively. No intra-familial clustering of specific depressive symptoms within families of depressed subjects could be observed.

Due to the inconsistencies in the clustering of individual symptoms in non-depressed and depressed relatives and the lack of intra-familial clustering, the familial aggregation of depression is unlikely to be caused by the aggregation of individual depressive symptoms. An inheritance of the vulnerability for complete depressive disorders influenced by environmental factors is more likely.

A link between older age of fatherhood and an increased risk of schizophrenia was detected in 1958. Since then, 10 studies attempted to replicate this result with different methods, on samples with different origins, using different age classes. Defining a cut-off at which the risk is significantly increased in the offspring could have an important impact on public health.

A meta-analysis (Meta Win®) was performed, assessing the mean effect size for each age class, taking into account the difference in age class references, and the study design.

An increased risk is detected when paternal age is below 20 (compared to 20–24), over 35 (compared to below 35), 39 (compared to less than 30), and 54 years old (compared to less than 25). Interestingly, 35 years appears nevertheless to be the lowest cut-off where the OR is always above 1, whatever the age class reference, and the smallest value where offspring of fathers below or above this age have a significantly different risk of schizophrenia.

No threshold can be precisely defined, but convergent elements indicate ages below or above 35 years. Using homogeneous age ranges in future studies could help to clarify a precise threshold.

Previous findings indicated that schizophrenia patients might have a different personality structure from the general population on several dimensions of temperament and character. Some authors proposed that HA might be a marker of underlying genetic vulnerability to schizophrenia. Studies on high-risk subjects and first degree relatives of patients is essential to test the value of a measure as a marker of genetic vulnerability to a disease. Few studies tested the biopsychosocial model of personality on unaffected relatives of schizophrenia.

We compared the Temperament and Character (TCI) profiles of 94 first degree relatives of schizophrenia and 75 controls. We also investigated the relationship between schizotypy and TCI dimensions in the study sample.

The harm avoidance scores of the relatives of schizoprenia patients with schizotypal features were significantly higher. Self transcendence scores were also significantly higher among relatives with schizotypal features. In contrast, the relatives of the patients with schizophrenia who did not have schizotypal features had higher SD and C scores than the control group.

This finding is consistent with the previous findings which suggested harm avoidance as a vulnerability indicator of schizophrenia. Some character features like self transcendence might be also associated with schizotypal features.

Executive dysfunctions have been studied as a potential endophenotype associated with the genetic basis of autism. Given that recent findings from clinical and molecular genetic studies suggest that autism and obsessive-compulsive disorder (OCD) could share a common pattern of heritability, we assessed executive functions as a possible common cognitive endophenotype in unaffected family members of individuals with either autism or OCD.

Five tests assessing executive functions (Tower of London, verbal fluency, design fluency, trail making and association fluency) were proposed to 58 unaffected first-degree relatives (parents and siblings) of probands with autism and 64 unaffected first-degree relatives of OCD patients. Results were compared with those of 47 healthy controls matched for age, sex, and level of education.

In the Tower of London test, both groups of unaffected relatives showed significantly lower scores and longer response times compared with controls. No differences were observed between autism and OCD relatives and healthy controls in the four other tasks (verbal fluency, design fluency, trail making test and association fluency).

Our findings show the existence of executive dysfunction in the unaffected first-degree relatives of probands with OCD, similar to those observed in the relatives of patients with autism. These results support and extend previous cognitive studies on probands indicating executive dysfunctions in autism and OCD. Planning and working memory processes could thus represent a common cognitive endophenotype in autism and OCD that could help in the identification of genes conferring vulnerability to these disorders.

To test the reliability and validity of the DIGS in Spanish population.

Inter-rater and test-retest reliability of the Spanish version of DIGS was tested in 95 inpatients and outpatients. The resultant diagnoses were compared with diagnoses obtained by the LEAD (Longitudinal Expert All Data) procedure as “gold standard”. The kappa statistic was used to measure concordance between blind inter-raters and between the diagnoses obtained by LEAD procedure and through the DIGS.

Overall kappa coefficient for inter-rater reliability was 0.956. The kappa value for individual diagnosis varied from major depression = 0.877 to schizophrenia = 1. Test-retest reliability was 0.926. Kappa for all individual target diagnoses ranged from 0.776 (major depression) to 1. Kappa between LEAD procedure and DIGS ranged from 0.704 (major depression) to 0.825 (bipolar I disorder).

Most of the DSM-IV major psychiatric disorders can be assessed with acceptable to excellent reliability with the Spanish version of the DIGS interview. The Spanish version of DIGS showed an acceptable to excellent concurrent validity. Giving the good reliability and validity of Spanish version of DIGS it should be considered to identify psychiatric phenotypes for genetics studies.

The family history is a widely used method in psychiatry; but data on the method's objectivity, reliability and validity shows partly diverging results.

In October 2005, a Medline search was conducted that yielded 7 studies regarding objectivity/reliability and 13 studies regarding validity. Results for six main groups of psychiatric diagnoses and any mental disorder were combined qualitatively for objectivity/reliability, and quantitatively for validity.

Objectivity was generally high (κ in the 0.80 range). Reliability was high for any mental disorder, schizophrenia, substance abuse and depression (κ in the 0.70 range), and low or medium for anxiety (κ between 0.30 and 0.50). Results on validity displayed an OR = 148 for the family history for schizophrenia; OR = 64 for mania/bipolar disorder; and OR's between 8 and 194 for substance abuse, between 3 and 37 for depression, between 5 and 350 for personality disorders, between 2.5 and 49 for anxiety, and between 2.4 and 9 for any mental disorder.

There is clear evidence that the family history provides results that are better than chance for all disorders examined. But variance among diagnostic groups and among studies is considerable.

To extensively review the European Court of Human Rights (ECHR) case law concerning psychiatric commitment, and to estimate the role of this supranational jurisprudence in the practice of contemporary psychiatry.

Using keywords to search the ECHR computerised database “HUDOC”, we reviewed all cases concerning psychiatric commitment registered between September 1953 and December 31, 2004. Four groups were identified: applications declared inadmissible; applications accepted but not judged by the Court; pending cases; and cases judged by the Court.

Of the almost 118,000 decisions taken by the ECHR in this time frame, we found 108 situations concerning psychiatric commitment. 41 of these applications were considered by the Court to be inadmissible. 24 other cases were considered admissible but not judged by the ECHR. Three admissible cases were still pending at the end of 2004. The ECHR judged 40 cases, and found in 35 of them that one or several rights as guaranteed by the Convention had been violated.

The ECHR protects the human rights of persons subjected to involuntary psychiatric commitment by creating supranational law in the following areas: definition of “unsoundness of mind”; conditions of lawfulness of detention; right to a review of detention by a Court; right to information; right to respect for private and family life; and conditions of confinement, which address inhuman and degrading treatment.

The respective number of applications submitted to the ECHR did not depend on when the Convention had entered into force in that country.

The possibility of an individual to access the ECHR depends on the degree of democracy in his country and on the access to legal assistance through non-governmental organisations or individual intervening parties.
