Prevalence of maternal antenatal anxiety and its association with demographic and socioeconomic factors: A multicentre study in Italy.

BACKGROUND: Maternal antenatal anxiety is very common, and despite its short- and long-term effects on both mothers and fetus outcomes, it has received less attention than it deserves in scientific research and clinical practice. Therefore, we aimed to estimate the prevalence of state anxiety in the antenatal period, and to analyze its association with demographic and socioeconomic factors. METHODS: A total of 1142 pregnant women from nine Italian healthcare centers were assessed through the state scale of the State-Trait Anxiety Inventory and a clinical interview. Demographic and socioeconomic factors were also measured. RESULTS: The prevalence of anxiety was 24.3% among pregnant women. There was a significantly higher risk of anxiety in pregnant women with low level of education (p < 0.01), who are jobless (p < 0.01), and who have economic problems (p < 0.01). Furthermore, pregnant women experience higher level of anxiety when they have not planned the pregnancy (p < 0.01), have a history of abortion (p < 0.05), and have children living at the time of the current pregnancy (p < 0.05). CONCLUSION: There exists a significant association between maternal antenatal anxiety and economic conditions. Early evaluation of socioeconomic status of pregnant women and their families in order to identify disadvantaged situations might reduce the prevalence of antenatal anxiety and its direct and indirect costs.

A randomised controlled trial of the effectiveness of a program for early detection and treatment of depression in primary care.

OBJECTIVE: There is considerable uncertainty about whether depression screening programs in primary care may improve outcomes and what specific features of such programs may contribute to success. We tested the effectiveness of a program involving substantial commitment from local mental health services. METHODS: Prospective, randomised, patient- and evaluator-masked, parallel-group, controlled study. Participants were recruited in several urban primary care practices where they completed the PC-SAD screener and WHOQOL-Bref. Those who screened positive and did not report suicidal ideation (N=115) were randomised to an intervention group (communication of the result and offer of psychiatric evaluation and treatment free of charge; N=56) or a control group (no feedback on test result for 3 months; N=59). After 3 months, 100 patients agreed to a follow-up telephone interview including the administration of the PC-SAD5 and WHOQOL-Bref. RESULTS: Depression severity and quality of life improved significantly in both groups. Intent-to-treat analysis showed no effect of the intervention. As only 37% of patients randomised to the intervention group actually contacted the study outpatient clinic, we performed a per-protocol analysis to determine whether the intervention, if delivered as planned, had been effective. This analysis revealed a significant positive effect of the intervention on severity of depressive symptoms, and on response and remission rate. Complier average causal effect analysis yielded similar results. CONCLUSION: Due to the relatively small sample size, our findings should be regarded as preliminary and have limited generalizability. They suggest that there are considerable barriers on the part of many patients to the implementation of depression screening programs in primary care. While such programs can be effective, they should be designed based on the understanding of patients' perspectives.

Diagnostic Accuracy of the Primary Care Screener for Affective Disorder (PC-SAD) in Primary Care.

BACKGROUND: Depression goes often unrecognised and untreated in non-psychiatric medical settings. Screening has recently gained acceptance as a first step towards improving depression recognition and management. The Primary Care Screener for Affective Disorders (PC-SAD) is a self-administered questionnaire to screen for Major Depressive Disorder (MDD) and Dysthymic Disorder (Dys) which has a sophisticated scoring algorithm that confers several advantages. This study tested its performance against a 'gold standard' diagnostic interview in primary care. METHODS: A total of 416 adults attending 13 urban general internal medicine primary care practices completed the PC-SAD. Of 409 who returned a valid PC-SAD, all those scoring positive (N=151) and a random sample (N=106) of those scoring negative were selected for a 3-month telephone follow-up assessment including the administration of the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID-I) by a psychiatrist who was masked to PC-SAD results. RESULTS: Most selected patients (N=212) took part in the follow-up assessment. After adjustment for partial verification bias the sensitivity, specificity, positive and negative predictive value for MDD were 90%, 83%, 51%, and 98%. For Dys, the corresponding figures were 78%, 79%, 8%, and 88%. CONCLUSIONS: While some study limitations suggest caution in interpreting our results, this study corroborated the diagnostic validity of the PC-SAD, although the low PPV may limit its usefulness with regard to Dys. Given its good psychometric properties and the short average administration time, the PC-SAD might be the screening instrument of choice in settings where the technology for computer automated scoring is available.

Psychopathological chronic sequelae of the 2009 earthquake in L'Aquila, Italy.

BACKGROUND: To date, there are no data available among the general adult population on the long-term psychological sequelae of the earthquake that occurred in the town of L'Aquila, Italy in 2009. We investigated the prevalence of post-traumatic stress disorder (PTSD) and major depression (MD) and identified risk factors for these disorders among adult survivors more than one year after the earthquake. METHODS: Telephone interviews were conducted among a random sample of 957 resident adults. The interviews were performed using a questionnaire on exposure to the earthquake, the Mini-International Neuropsychiatric Interview for PTSD, and the Patient Health Questionnaire 8 for MD. Univariate and multivariate logistic regression analyses were conducted to assess potential risk factors. RESULTS: The prevalence rates of PTSD and MD were 4.1% (95% CI=3.0-5.5) and 5.8% (95% CI=4.5-7.5), respectively. The risk factors for PTSD were economic difficulties not necessarily related to the earthquake, chronic disease, death of a relative or friend, and serious economic difficulties as consequence of the earthquake, whereas those for MD were female gender, economic difficulties not necessarily related to the earthquake, not having a permanent job and living in L'Aquila. LIMITATIONS: The major limitations were the cross sectional design and the uncertain accuracy of the diagnoses compared with clinical diagnoses. CONCLUSIONS: Psychological symptoms are frequent even 14-19 months after the L'Aquila earthquake. The mental health care providers in the area of L'Aquila should be aware of the possibility of PTSD or MD among their users.

Development and preliminary validation of the PC-SAD5, a screener-derived short depression severity measure.

BACKGROUND: The prevalence of depressive disorders is high among patients with skin disease. The PC-SAD is a 37-item self-administered depression screening questionnaire that has been validated in dermatological patients. OBJECTIVE: The aim of this study was to develop and validate a brief depression severity instrument derived from the PC-SAD that can be used to assess severity and monitor ongoing clinical course. METHODS: Two patient samples participated in the study: 72 adult dermatological inpatients and 73 adults attending six primary care practices. Psychiatric assessment included the Structured Clinical Interview for DSM-IV and an 18-item version of the PC-SAD; moreover, dermatological patients completed the Patient Health Questionnaire depression scale (PHQ-9), while primary care patients were administered the Montgomery-Asberg Depression Rating Scale (MADRS). A subset of five PC-SAD items showing the best psychometric properties were selected, and the reliability and validity of the resulting instrument (PC-SAD5) were examined. RESULTS: The PC-SAD5 showed satisfactory internal consistency in both samples. There was a high correlation between PC-SAD5 and PHQ-9 and MADRS scores. Multiple regression analysis revealed a gradient of PC-SAD5 scores from patients with no mental disorder, those with milder forms of depression, to those with Major Depressive Disorder. Similar results were observed for the 18-item version of the PC-SAD. CONCLUSION: The availability of valid and reliable continuous measures of depression severity derived from the PC-SAD extends its field of application from depression screening to use as a follow-up measure of depression severity in routine clinical practice. A validated very short instrument such as the PC-SAD5 may have substantial clinical value.

Psychological well-being (PWB): a natural life outlook? An Italian twin study on heritability of PWB in young adults.

BACKGROUND: To date, the genetic and environmental architecture of the dimensions of psychological well-being (PWB) remains unexplored. METHOD: PWB of 742 twins aged 23-24 years and enrolled in the Italian Twin Registry was assessed with the three-item version of Ryff's Scales of Psychological Well-Being (SPWB). These scales include items for evaluating the PWB dimensions of self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth. A twin design was used to obtain correlations in the PWB dimensions for monozygotic (MZ) and dizygotic (DZ) twins and to estimate the contribution of genetic and environmental factors to variation and covariation in the dimensions. RESULTS: Genetic factors explained moderate to substantial proportions of variance in the six SPWB dimensions, with heritability estimates between 37% and 64%. The estimates of genetic correlations were very high (range 0.77-0.99), indicating that genetic factors that influence the expression of the different dimensions of PWB may be shared to a large extent. Non-shared environmental correlations ranged from substantial to high, with the exception of the correlation between autonomy and the dimensions of purpose in life, self-acceptance and personal growth. CONCLUSIONS: This study presents a twin analysis of PWB measured by the SPWB dimensions; it was found that both genes and non-shared environment play a role in individual differences. The genetic and non-shared environmental correlations between SPWB dimensions suggest that common underlying genetic and non-shared environmental factors influence the expression of the different facets of PWB.

[The principles in the evaluation of the efficacy of health and social interventions]. / I principi nella valutazione scientifica dell'efficacia degli interventi socio-sanitari resi facili per tutti: le 10 C.

The 10 Cs are a reminder of the principles that should lead any evaluation of the efficacy (i.e. the capacity to attain the specific objectives, in case of health services better health outcomes) of any intervention. They are: 1. Comparison with other treatment; 2. Comparability of compared groups; 3. Comparability of data collection; 4. Completeness of collected outcomes; 5. Completeness of follow-up; 6. Consistency of treatments; 7. Casuality (consideration of); 8. Consistency of investigated patients with patients who are treated in daily practice; 9. Continuity of surveillance; 10. Costs. The paper describes the almost total lack of effective treatments and of methods to test their efficacy till the beginning of 1800 and the gradual raise of the randomised controlled trial as the gold standard method for such an evaluation. It explain the 10 Cs with analogies from a less emotionally loaded area, that of teaching methodologies. It deals with the value and limit of single case description and hints to the ethical problems of doing or not doing a controlled trial, using Semmelweis and Pap test examples.

Development, reliability and validity of a self-administered questionnaire on subjective opinion about delusions and voices.

OBJECTIVE: This study focuses on the psychometric characteristics of a self-report instrument, the Delusion and Voices Self-Assessment (DV-SA) questionnaire, to assess delusions and auditory hallucinations from the clients' perspective. METHODS: The DV-SA was administered to 70 schizophrenic patients in treatment in an outpatient mental health clinic in Naples, Italy. It was administered twice to determine the test-retest reliability. A clinician who was blind to the patients' DV-SA ratings also rated the Brief Psychiatric Rating Scale (BPRS). Sensitivity to change was assessed in 30 patients who completed a 24-week course of cognitive-behavioural therapy sessions. RESULTS: The DV-SA showed good internal consistency and structure, and an acceptable average of item-total correlation. The test-retest reliability was very satisfactory. The comparison between DV-SA and BPRS showed a good association for illness severity. CONCLUSIONS: The DV-SA may be a reliable, valid and sensitive instrument for assessing subjective experiences on delusions and auditory hallucinations. The brevity and limited need for assistance make it an efficient instrument to assess patients' evolution during therapy.

Discriminant ability and criterion validity of the HoNOS in Italian psychiatric residential facilities.

BACKGROUND: The Health of the Nation Outcomes Scales (HoNOS) was developed as an inclusive and comprehensive instrument to assess patient outcomes in 4 main domains: behaviour, cognitive and physical impairment, symptoms and social functioning/context. Concerns about the reliability and validity of the HoNOS have been raised. The aim of this study was to further investigate the discriminatory ability of the HoNOS; criterion validity was also examined. SAMPLING AND METHODS: A broad sample of patients with psychotic disorders, admitted to 265 Italian residential facilities, were rated by trained research assistants and local staff on the HoNOS, Global Assessment of Functioning, Life Skills Profile, and Physical Health Index. Discriminant function analysis was used to examine the ability of the HoNOS items to correctly classify patients with positive symptoms, substantial psychosocial impairment or physical disability. The HoNOS criterion validity was also examined. RESULTS: On the whole, the pattern of correlations between the HoNOS and the other corresponding measures was consistent. However, the majority of the correlations were only moderate. In discriminant function analysis, the classification procedure correctly classified 55.7% of the patients. CONCLUSIONS: Although the HoNOS has many advantages in its brevity, it may lack sufficient discriminatory ability for certain patient groups. Further, it correlates only moderately with measures of disability and physical health status. These findings suggest that the HoNOS alone might be insufficient for routine evaluation and should probably be supplemented by additional measures.

Quality of psychiatric care: validation of an instrument for measuring inpatient opinion.

OBJECTIVES: To validate a brief self-completed questionnaire for routinely assessing patients' opinions on the quality of care in inpatient psychiatric wards (Rome Opinion Questionnaire for Psychiatric Wards). DESIGN: A preliminary version was assessed for face and content validity by eight psychiatrists and two patient focus groups. The final version was evaluated for acceptability, factor structure, internal consistency, and test-retest reliability. SETTING: An inpatient psychiatric ward in a general hospital in Rome. STUDY PARTICIPANTS: The questionnaire was administered to all consecutive inpatients admitted over a 6-month period (n = 169). Test-retest reliability was evaluated by administering the questionnaire for a second time to 27 inpatients. MAIN OUTCOME MEASURES: Face and content validity: psychiatrists and focus groups' opinions on relevance, importance, and clarity, acceptability: inpatients' opinions on user-friendliness; factor analysis: principal component analysis; internal consistency: Cronbach's alpha; test-retest reliability: Cohen's weighted kappa coefficient, intraclass correlation coefficient RESULTS: After evaluating face and content validity, the questionnaire was reduced to 10 items. Inpatients found the questionnaire to be acceptable. Factor analysis revealed that three factors-professional qualities of staff, information received, and physical environment-explained 67.2% of total variance. Cronbach's alpha was 0.82 for the questionnaire and 0.61, 0.71, and 0.35 for the three factors, respectively. Test-retest reliability was good; weighted kappa higher than 0.9 for three items and 0.6-0.9 for seven items. The intraclass correlation coefficient was 0.80. CONCLUSIONS: The questionnaire seems to be adequate for evaluating patients' opinions on care in inpatient psychiatric wards. Because of its user-friendliness, it may be particularly suitable for routine use.
