ABSTRACT The current study aims to compare telephone vs face-to-face administration of the version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, (SCID) for diagnosis of "any psychotic disorder" in a clinical population in Iran.
The sample consisted of 72 subjects from 2 psychiatric outpatient services in Tehran, Iran. The subjects were interviewed using face-to-face SCID for the purpose of diagnosing psychotic disorders. A second independent telephone SCID was administered to the entire sample within 5 to 10 days, and the lifetime and 12-month diagnoses were compared.
The positive likelihood ratio of telephone-administered SCID for diagnosis of "any lifetime psychotic disorder" was 5.1 when compared with the face-to-face SCID. The value for the primary psychotic disorders in the past 12 months was lower (2.3).
The data indicate that telephone administration of the SCID is an acceptable method to differentiate between subjects with lifetime psychotic disorders and those who have had no psychotic disorders and provides a less resource-demanding alternative to face-to-face assessments.

    ABSTRACT: Postnatal depression (PND) is the most common disorder of the puerperium with serious consequences for both mother and child if left untreated. While there are effective treatments, there are many barriers for new mothers needing to access them. Prevention strategies may offer a more acceptable means of addressing the problem. Internet interventions can help overcome some barriers to reducing the impact of PND. However, to date there are no published studies that investigate the efficacy of internet interventions for the prevention of PND.Methods/design: The proposed study is a two-arm double blind randomised controlled trial. 175 participants will be recruited in the immediate postnatal period at an Australian community hospital. Women who meet inclusion criteria (internet access, email address, telephone number, over 18, live birth, fluent English) will complete the Edinburgh Postnatal Depression Scale (EPDS). Those with a score above 9 will undertake the Structured Clinical Interview for DSM Disorders (SCID). Those with a clinical diagnosis of depression, or a lifetime diagnosis of bipolar disorder or psychosis on the SCID will be excluded. Following completion of the baseline battery women will be randomised using a computer-generated algorithm to either the intervention or control condition. The intervention will consist of 5 modules of automated, interactive cognitive behaviour training (CB training), completed weekly with email reminders. The control will replicate the level of contact participants experience with the intervention, but the content will be of a general health nature. Participants will complete questionnaires immediately post-intervention (6 weeks) and 3-, 6- and 12 months follow-up. There will also be a second SCID delivered via telephone at 6 months. We hypothesise that relative to the control group, the intervention group will show a greater reduction in postnatal distress on the EPDS (primary outcome measure). We also hypothesise that the intervention group will demonstrate lower levels of anxiety and stress and higher levels of parenting confidence than the control group following intervention and/or follow-up. The proposed study addresses a number of limitations of earlier trials.Trial registration: ACTRN12609001032246.

    ABSTRACT: For reasons of feasibility, diagnostic telephone interviews are frequently used in research of psychiatric morbidity. However, it is unknown whether diagnostic telephone interviews are as valid as diagnostic face-to-face interviews. Are diagnostic telephone interviews for psychiatric disorders as valid as diagnostic face-to-face interviews? A systematic review of original studies in PubMed, PsychINFO and Embase was carried out. We included studies considering (1) the sensitivity and specificity of diagnostic telephone interviews using face-to-face interviews as a golden standard and (2) the agreement between diagnostic telephone and diagnostic face-to-face interviews. Eligible were studies in the general population, in patients at risk for psychiatric disorders and in psychiatric outpatients. We assessed risk of bias with the quality assessment of diagnostic accuracy studies (QUADAS) instrument. We included sixteen studies. The included studies were generally small with thirteen studies reporting about <100 participants. Specificity was generally high in populations with low or intermediate prevalence of psychiatric morbidity. Sensitivity was low in these populations, but slightly higher in samples with more psychiatric disorders. Studies with a higher risk of psychiatric disorders generally reported higher percentages of agreement and higher kappa values. Considering the QUADAS-2 criteria, most studies had a medium or high risk of bias, especially concerning patient selection and unbiased judgement of the test. Of the six studies with a medium or low risk of bias, the three studies assessing current anxiety and depressive disorders yielded kappa values between 0.69 and 0.84, indicating good agreement. There is insufficient evidence that diagnostic telephone interviews for the diagnosis of psychiatric disorders are valid, although results for depression and anxiety disorders seem promising.
