EFTA00024175 | EFTA00024213 Precictors of delayed disclosure of rape family structure was complete, i.e., whether the biological parents were living together (yes/no). Patients were then asked to confirm the presence of prior negative sexual experiences (yes/no), and whether they had a current sexual relationship (yes/no). Rape characteristics Information about date and time of the rape was obtained to calculate the time since rape at admission. Next, patients were requested to describe the rape. Their response was categorized into use of penetration (yes/no), group rape (yes/no), use of physical violence (yes/no), and use of threats verbally and/or with a weapon (yes/no). Also, information regarding the victim's relationship to the assailant was obtained. The assailant was defined as a stranger when the victim had never been in contact with the assailant before the rape. Responses were used to form a closeness category (yes in case of family, (boy) friend, or mentor). Patients were also asked about the (estimated) age of the assailant (categorized into 12-17 years or > 18 years), and whether the victim had used alcohol prior to the rape (yes/no). Post-rape characteristics Patients were asked when they first talked about the rape. The response was used to calculate the disclosure time and the help-seeking time. At the end of the interview, patients were asked whether they had reported to the police after the incident (yes/no), and whether they had received any medical care after the incident (yes/no). The study was performed in accordance with the precepts and regulations for research as stated in the Declaration of Helsinki, and the Dutch Medical Research involving Humans Subjects Act concerning scientific research. According to the Ethical Medical Committee of the University Medical Centre Utrecht, this act was not applicable to the present study. Written informed consent was obtained from both patients and parents. Measures Posttraumatic stress The Children's Responses to Trauma Inventory (CRTI; Alisic, Eland, & Kleber, 2006) was used for participants aged 12-18 years. This is a 34-item questionnaire assessing severity of PTSD symptoms according to DSM-IV. Patients are asked to indicate to what extent a reaction to a traumatic event was present during the past week. Scores range from I to 5, with higher scores indicating more symptomatology. The four subscales: Intrusion, Avoidance, Arousal, and Other Child-Specific Reactions consist of 7, 11, 6, and 10 items, respectively. The reliability of this instrument is good to excellent (Cronbach's a 0.92 for total score, 0.79 for Intrusion, 0.77 for Avoidance, 0.71 for Arousal; Alisic & Kleber. 2010). For the purpose of the study, only the total score was analysed. Depression Children Depression Inventory (CDI; Kovacs, 1992; Timbremont & Braet, 2002) was used for participants aged 12-17 years of age. The CDI is a 27-item questionnaire, assessing cognitive, affective, and behavioural symptoms of depression. The Dutch CDI has a satisfactory internal consistency, with Cronbach's a ranging between 0.71 and 0.89 (Timbremont & Braet, 2002). Behavioural problems The Youth Self-Report (YSR; Achenbach & Rescorla, 2001) was used for participants aged 12—I8 years. This questionnaire evaluates the teenager's perception of behavioural and emotional problems. YSR has shown to be internally reliable (Cronbach's a's ranging from 0.71 to 0.95), and convergent and discriminant validity is reported to be satisfactory (Berube & Achenbach, 2006). The YSR includes four broadband scales and nine narrow-band scales to assess behaviour problems. For the purpose of the study, only the total score on behaviour problems was included in the analyses. General psychopathology The Symptom Checklist-90-R (SCL-90-R; Arrindell & Ettema, 1986) was used for participants aged 12-25 years. This is a 90-item self-report inventory to assess psychosocial distress. Patients were instructed to indicate the amount they were bothered by each of the distress symptoms during the preceding week. Patients rated 90 distress symptoms on a five-point Liken scale with being "not at all" and 5 being "extremely." The statements are assigned to eight dimensions, reflecting various types of psychopathology: anxiety, agoraphobia, depression, somatization, insufficiency, sensitivity, hostility, and insomnia. The Global Severity Index (GSI) can be used as a summary of the test and reflects the severity of all answered statements as a global measure of distress. Cronbach's a has been found to range from 0.73 to 0.97. For the purpose of the study, only the GSI was analysed. Data analyses To compare demographic and post-rape characteristics between the early and delayed disclosers, chi-square tests were used. To compare multiple continuous psychological scores, MANCOVA was used with "time since trauma" as a covariate to correct for the potential influence of time since trauma. Delayed disclosure was used as a dependent variable. The strength of the univariate associations between each potential risk factor and delayed disclosure was estimated by calculating the odds ratio (OR) along with 95% confidence intervals (95% CI). To determine the strongest risk factors for delayed disclosure, each potential risk Citation: Eurccean Jame) of Psychoireumacology 2015. 8: 25883 ritip://cbc.dol.mgn0.3402teipt.v8.25883 3 (pope rwmber no. oor noon puma* EFTA00024213

✅ The Spanish DP-3 showed good internal consistency (Cronbach’s α > 0.7), acceptable structural validity (CFI = .924, TLI = .848), and high sensitivity to developmental change across repeated assessments. It also correlates with the gold-standard BSID-III.

Reviewer asked something similar for a recent paper on disgust (doi.org/10.1371/jour... ), and we wrote what’s in the image. TL;DR: behaviour can be as good as self-report, and is substantially more robust against demand effects. (CC @tahnee-engelen.bsky.social and @nicolecrust.bsky.social)
Paragraph from Edgar et al. (2024, PLOS ONE): “The summarised studies mostly rely on self-report measures of disgust elicited by written or picture stimuli. Such self-report measures can have excellent psychometric properties, for example the internal consistency [6] and external agreement with others’ ratings [20] of the Three-Domain Disgust Scale, or the high test-retest reliability of self-reported disgust for images [12]. While experimental tasks are often less reliable than self-report measures [21], behavioural disgust avoidance measured in preferential looking tasks has excellent internal consistency, Spearman-Brown ρ = 0.81 to 0.94 and Cronbach’s α = 0.78 to 0.91 [22], and test-retest reliability equal to self-reported disgust ratings [12]. Behavioural disgust avoidance correlates with self-reported disgust sensitivity, R = 0.28 to R = 0.34 [12], and with self-reported disgust ratings for stimuli, R = 0.19 to 0.50 [22]. However, a major difference between self-report and behavioural measures of disgust avoidance is that self-reported disgust shows a very large (Cohen’s d = 1.25) placebo effect, whereas oculomotor avoidance (gaze dwell time) in preferential looking tasks only shows a small to medium (Cohen’s d = 0.44) effect [23].”

Validated self-administered screening tools to identify depression among young adults (18 to 25-years-old) in East Asia and the Pacific Region low-and-middle income countries (LMICs): A systematic review by my PhD student Dennis Dantic. https//www.science... @ucl-primarycare.bsky.social
tools for symptoms of depression among young adults (18 to 25 years old) in East Asia and the Pacific. A total of 22 studies with 24,069 participants were included, covering both clinical and non-clinical populations. Nine selfadministered screening tools were identified, with Patient Health Questionnaire-9 (PHQ-9), Patient Health Questionnaire-2 PHQ-2, and Centre for Epidemiological Studies Depression (CES-D) being the most frequently studied. PHQ-9 demonstrated moderate to excellent internal consistency reliability, with Cronbach’s alpha ranging from 0.67 to 0.92, and a pooled AUC of 0.86, indicating strong screening accuracy. PHQ-2, showed an Area Under the Curve (AUC) of 0.85, high sensitivity (0.96), and moderate specificity (0.80). CES-D exhibited an AUC of 0.87, good sensitivity (0.81), and specificity (0.78), with high heterogeneity (I² = 74.70 %–86.69 %). The meta-analysis revealed substantial variability in sensitivity and specificity across settings, with differences in study methodologies, cutoff scores, and reference standards contributing to high heterogeneity. Additionally, 95.5 % of studies had a moderate risk of bias in patient selection, affecting generalizability. Despite these limitations, PHQ-9, PHQ-2, and CES-D remain valuable tools for identifying symptoms of depression among young adults. The accessibility, ease of administration, and strong psychometric properties of these tests support their continued use in resource-limited settings, though standardization of methodologies and expanded regional validation are needed to improve screening accuracy and applicability.

Does anyone have the British Ability Scales (BAS) II manual (Elliott, Smith & McCulloch, 1996/1997) on their shelf? 📚

@magdamatetovici.bsky.social, @carorowland.bsky.social & I are trying to look up the reliability for the Naming Vocabulary subtest (age 5). E.g. Cronbach’s α or test–retest r.

I've added a new example to our paper's repo, demonstrating how our reliability method replicates Cronbach's alpha for a simple model, but also how our method can account for: (i) binary data, (ii) varying numbers of items per pps, & (iii) improvement over trials www.bignardi.co.uk/8_bayes_reli...

Good: I have recalculated Cronbach's alpha the right way (argh that I did it wrong before), run my two-tailed t-tests, and run my one-way ANOVAs. I even edited the tables so they look right (in Scrivener at least). Also, they're contacting my references for the job.

I mean, to the extent that cutoffs make sense (they don't), you're looking at the same for alpha, as the two are strongly correlated (with exceptions). However, we think using cutoffs hasn't really worked out well for Cronbach's alpha: journals.sagepub.com/doi/full/10....
