“…When asked if their current health was ‘Poor’, ‘Fair’, ‘Good’, ‘Very good’, or ‘Excellent’, 77% (17/22) of women in usual care and 71% (24/34) of women in Group Care rated their health as ‘Very Good’ or ‘Excellent’. One of the ten items in the EPDS was accidentally omitted ( I have been so unhappy that I have had difficulty sleeping ), so we used the validated 5-question version – EPDS-Dep-5 [ 23 ] to report on here. The EPDS-Dep-5 score is calculated using five questions from the original EPDS—‘ I have been able to laugh and see the funny side of things ’, ‘ I have looked forward with enjoyment to things ’, ‘ I have felt sad or miserable ’, ‘ I have been so unhappy that I have been crying ’, and ‘ The thought of harming myself has occurred to me ’ (Cronbach’s alpha 0.82 compared to 0.88 for the full EPDS).…”

Background In group-based pregnancy models, antenatal care and childbirth/parenting education are provided in groups of eight to 10 women, usually with two midwives, and six to eight sessions. Current evidence is inconclusive regarding potential benefit or harm. We aimed to explore the feasibility of implementing an adequately powered randomised controlled trial (RCT). Methods A two-arm pilot RCT was conducted in a tertiary maternity hospital in Melbourne, Australia. Women were randomly allocated to either the intervention to receive group-based antenatal care and education (group care) or to usual care, which included hospital-based midwife, caseload midwifery, team midwifery, or GP shared care. Participants were English-speaking, primiparous, low risk, and < 24 weeks gestation at booking. Data collection: feasibility measures throughout pilot, baseline questionnaire at recruitment, clinical outcome data from the medical record, and a telephone-administered questionnaire 6 weeks postpartum. A focus group explored midwives’ views. Results Seventy-four women were recruited from May to June 2017 (group care = 40, usual care = 34). Study uptake was 35%. Women allocated to group care rated their overall pregnancy care more highly (88% good/very good vs 77% in usual care). There was no evidence of harm related to group care. Overarching themes from the midwives were that group care helped ‘build connections’ and ‘empower women’. All midwives would work in the model again and believed it should be expanded. Conclusion Group care was acceptable to both women and midwives with no evidence of harm. The pilot demonstrated the feasibility of undertaking a large adequately powered RCT, important given the inconclusive evidence on clinical outcomes regarding the model, and its current relatively widespread implementation.

“…From this model, for each set of HADS-D and HADS-T paired cutoffs, we estimated the difference in sensitivity and specificity between the two tests and associated CIs. These CIs from the bootstrap approach and individual-level analysis allowed us to test whether the sensitivity and specificity of the HADS-T is equivalent to that of the HADS-D based on a prespecified equivalence margin of δ = 0.05 (Walker & Nowacki, 2011), as we have done in previous studies (Harel et al, 2021; Ishihara et al, 2019; Wu, Levis, Riehm, et al, 2020).…”

The seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item HADS (HADS-T) are both used for major depression screening. Compared to the HADS-D, the HADS-T includes anxiety items and requires more time to complete. We compared the screening accuracy of the HADS-D and HADS-T for major depression detection. We conducted an individual participant data meta-analysis and fit bivariate random effects models to assess diagnostic accuracy among participants with both HADS-D and HADS-T scores. We identified optimal cutoffs, estimated sensitivity and specificity with 95% confidence intervals, and compared screening accuracy across paired cutoffs via two-stage and individual-level models. We used a 0.05 equivalence margin to assess equivalency in sensitivity and specificity. 20,700 participants (2,285 major depression cases) from 98 studies were included. Cutoffs of ≥7 for the HADS-D (sensitivity 0.79 [0.75, 0.83], specificity 0.78 [0.75, 0.80]) and ≥15 for the HADS-T (sensitivity 0.79 [0.76, 0.82], specificity 0.81 [0.78, 0.83]) minimized the distance to the top-left corner of the receiver operating characteristic curve. Across all sets of paired cutoffs evaluated, differences of sensitivity between HADS-T and HADS-D ranged from −0.05 to 0.01 (0.00 at paired optimal cutoffs), and differences of specificity were within 0.03 for all cutoffs (0.02–0.03). The pattern was similar among outpatients, although the HADS-T was slightly (not nonequivalently) more specific among inpatients. The accuracy of HADS-T was equivalent to the HADS-D for detecting major depression. In most settings, the shorter HADS-D would be preferred.

“…This forms a series of candidate sets to be chosen from. In the third step, the smallest candidate set from step 2 that satisfies the pre‐specified criteria is selected as the optimal short form (Harel et al, 2021). Thus, the OTA is objective, with different researchers using the same set of pre‐specified criteria will obtain the same optimal short form (Harel et al, 2019).…”

“…This avoids subjectivity in conventional item selection approaches, which may lead researchers to arrive at different short forms even using the same approach. Despite OTA being relatively new, several studies have demonstrated the robustness of using objective and predetermined criteria for item selection (Harel et al, 2019; Harel et al, 2021; Li, Fong, et al, 2020; Xiao et al, 2022). However, there has been no application of OTA in the field of nursing research.…”

Aim: To develop and psychometrically test shortened 37-item Chinese Work Readiness Scale for Graduate Nurse without compromising its reliability and validity.Design: Two cross-sectional studies.Methods: Data were obtained from two cross-sectional online surveys on the same target group of newly graduated nurses in China. The two periods of data collection were from June to August 2018 and from June and July 2021, with 1348 respondents completing the 37-item Chinese Work Readiness Scale for Graduate Nurse. The optimal test assembly procedure based on a generalized partial credit model was adopted to shorten the scale. Results:The mean age of the 1348 nurses was 22.3 years (standard deviation = 1.5), with 1257 (93.2%) being female. The category characteristic curve showed that a 5-point Likert scale was adequate in lieu of the original 10-point Likert scale. The optimal test assembly procedure identified a 17-item version that maintained at least 0.9 correlation with the full scale, a Cronbach's alpha of at least 0.9, and at least 70% of the test information retained. Its discrimination parameters ranged from 1.68 to 2.84, whereas the difficulty parameters were monotonic and ranged from −4.50 to 1.56. When retaining only 50% of test information, a 9-item version was obtained. Its discrimination parameters ranged from 1.84 to 4.55, and difficulty parameters ranged from −3.37 to 1.15. The Cronbach's alphas for the 17-item and 9-item versions were 0.97 and 0.95 respectively.Conclusions: Both the 17-item and 9-item versions are appropriate for assessing registered nurses' work readiness, with the 9-item version demanding more subjects to compensate for the reduced information. Optimal test assembly approach is appropriate in shortening self-reported scales in the nursing field, while retaining satisfactory levels of reliability, validity, test information and conceptual adequacy. Patient or Public Contribution:This study involved graduate nurses who provided responses to the test scale and experts who contributed to the content validation.
