Norms According to Age and Gender for the Spanish Version of the Inventory of Depression and Anxiety Symptoms (IDAS-II)

Abstract

Inventory of Depression and Anxiety Symptoms-II (IDAS-II) constitutes a useful measurement tool with demonstrated psychometric properties that is contributing to the advancement of knowledge of emotional disorders within transdiagnostic models. To implement its use in clinical settings it is important that the scores can be interpreted in order to guide clinical decisions. This study aims to develops normative data for the Spanish version of the IDAS-II. An anonymous online survey was applied to 1,072 subjects, recruited through a stratified random sampling procedure taking into account population gender, age, and geographical region of Spain. Results show that women tend to score higher than men, particularly on the Dysphoria, General Depression, Appetite Gain, and Lassitude scales. Largest effect sizes for differences in the scores according to age were found for Lassitude, Dysphoria, and General Depression. Therefore, normative data according to gender and age group for each IDAS-II scale is provided. The norms provided in this work complement those already available, facilitating the decision-making of clinical professionals. Evidence of unidimensionality is provided for the 19 IDAS-II scales that allows researchers and clinicians to use specific IDAS-II scales independently.

Assessing Internalizing Symptoms and Their Relation with Levels of Impairment: Evidence-Based Cutoffs for Interpreting Inventory of Depression and Anxiety Symptoms (IDAS-II) Scores

“…The current study presents novel evidence on the clinical utility of IDAS-II scores by providing information about the associated degree of impairment. The IDAS-II has demostrated to be a reliable (De la Rosa-Cáceres et al, 2020;Irak & Albayrak, 2020;Sanchez-Garcia et al, 2021;Watson et al, 2012) and useful assessment measure of internalizing symptoms in research using a transdiagnostic approach to emotional disorders (Kotov et al, 2017). Present results complement previous evidence, by bringing forth reliable cutoffs that differentiate patient and community samples and by estimating cutoffs of IDAS-II scales associated with different levels of impairment that can help clinicians with therapeutic planning.…”

“…Second, data from the community sample was collected online, a procedure that, according to Arditte et al (2016), could lead to higher psychopathological scores compared to other traditional data collection procedures. However, the study by Sanchez-Garcia et al (2021) using the same data set showed that these do not differ from data from other Spanish samples collected by traditional methods (De la Rosa-Cáceres et al, 2020) nor from the American normative sample used by Nelson et al (2018). Further, a comparative study by Weigold et al (2013) indicated equivalence across paper-and-pencil and internet-based data collection methods.…”

Romanian Inventory of Depression and Anxiety Symptoms (IDAS-II)

“…Given the preponderance of women in our sample, this might have an influence on depression and anxiety dimensions. Although the smaller sample for the additional analyses on a gender-balanced sub-samples limits the interpretation of the results, we note that they are suggestive of the fact that the Romanian version of the IDAS-II could capture expected differences in age and gender, based on previously published norms (Sanchez-Garcia et al, 2021).…”

“…The IDAS-II can be a useful tool to gather evidence on the structure of internalizing dimensions within the HiTOP model and to Sanchez-Garcia et al, 2021;Wester et al, 2022), as well as between various levels of impairment (De la Rosa-Cáceres et al, 2023).…”

Depression, Anxiety and Antidepressants and Anxiolytics Use in Spanish Informal Caregivers according to the Physical Activity Frequency: EHSS 2014–2020

“…It has been observed that immigrants living in Spain have a higher prevalence of suffering from depression or anxiety compared to the native population [ 6 ]. We also found that women have a higher rate of depression and anxiety than men in Spain [ 7 ]. This pathology is usually combated with psychological treatments and/or antidepressant drugs, such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants [ 4 ].…”
