Description

The Immigrant Acculturation Scale (IAS-23) is a standardized psychometric instrument designed to assess the degree of cultural adaptation and acculturation among immigrants residing in Greece. The questionnaire provides a multidimensional evaluation of the psychological, social, and cultural processes through which immigrants adjust to the linguistic, interpersonal, and cultural environment of the host country while preserving important aspects of their original cultural identity. Developed specifically for immigrant populations living in Greece, the IAS-23 offers a comprehensive framework for understanding how cultural adaptation influences psychosocial functioning, social participation, and overall quality of life.

Acculturation is a dynamic and continuous process involving cognitive, emotional, behavioral, and social changes that emerge when individuals from different cultural backgrounds come into prolonged contact. Successful acculturation is associated with improved psychological adjustment, stronger social integration, greater participation in community life, enhanced communication skills, and better overall well-being. Conversely, difficulties in cultural adaptation may contribute to acculturative stress, social isolation, discrimination, anxiety, depression, and reduced quality of life.

The questionnaire consists of 23 self-report items that evaluate multiple dimensions of cultural adaptation, including Greek language proficiency, participation in social and community activities, interpersonal relationships, adoption of cultural values and social norms of the host society, maintenance of cultural identity, and adjustment to everyday life in Greece. Its brief administration time of approximately 6–12 minutes makes it suitable for both large-scale research and routine clinical assessment. The IAS-23 was initially administered to 150 immigrants living in Greece who attended a major psychiatric institution in Athens, providing the basis for its initial psychometric evaluation.

The IAS-23 is widely applicable in cross-cultural psychology, psychiatry, migration studies, sociology, public health, community mental health, behavioral medicine, social work, educational research, epidemiology, and healthcare services, where it serves as an important instrument for evaluating cultural adaptation, identifying vulnerable populations, and supporting the development of culturally sensitive interventions and public health policies.

Data Analysis and Use

Data obtained from the Immigrant Acculturation Scale (IAS-23) are analyzed using comprehensive psychometric and statistical procedures designed to evaluate immigrants’ level of cultural adaptation and its association with psychological, behavioral, and social outcomes. Participants’ responses are transformed into quantitative scores representing overall acculturation and the principal dimensions of linguistic, social, and cultural adaptation.

Psychometric evaluation typically includes analyses of internal consistency using Cronbach’s alpha coefficient, together with assessments of test–retest reliability, construct validity, content validity, criterion validity, convergent validity, discriminant validity, and exploratory and confirmatory factor analyses (EFA/CFA) to verify the theoretical structure of the questionnaire. Additional analyses may include measurement invariance across demographic and cultural groups, composite reliability, and item-response analyses to ensure robust psychometric performance.

Statistical procedures frequently involve descriptive statistics, calculation of means and standard deviations, Pearson or Spearman correlation analyses, multiple linear regression, hierarchical regression, structural equation modeling (SEM), mediation and moderation analyses, multilevel modeling, latent profile analysis, and longitudinal investigations examining the relationships between acculturation, acculturative stress, psychological well-being, anxiety, depression, resilience, quality of life, social support, healthcare utilization, and community participation.

The findings can be applied in migration research, clinical psychology, psychiatry, public health, community mental health services, and social policy. They support clinicians, psychologists, social workers, educators, and policymakers in identifying individuals experiencing adaptation difficulties, evaluating psychosocial interventions, monitoring cultural integration over time, and designing evidence-based programs that promote successful integration and social inclusion.

Objective

The primary objective of the Immigrant Acculturation Scale (IAS-23) is to provide a reliable, valid, and culturally sensitive assessment of the level of acculturation among immigrants living in Greece. The questionnaire enables researchers, psychologists, psychiatrists, social workers, public health professionals, and community organizations to evaluate how effectively immigrants adapt to the linguistic, social, and cultural environment of the host society while preserving important aspects of their cultural heritage.

The instrument facilitates the investigation of the relationship between cultural adaptation and psychological functioning by examining how acculturation influences emotional well-being, stress-related psychological manifestations, anxiety, depression, resilience, social participation, and overall psychosocial adjustment. Furthermore, it contributes to identifying both protective and risk factors associated with successful integration, thereby supporting the development of culturally appropriate healthcare services, educational initiatives, community interventions, and evidence-based migration policies.

The IAS-23 is particularly valuable in cross-cultural psychology, psychiatry, sociology, migration studies, public health, social work, community mental health, behavioral medicine, epidemiology, and intercultural research, where systematic assessment of acculturation contributes to improving both scientific knowledge and culturally competent professional practice.

Scoring

The Immigrant Acculturation Scale (IAS-23) consists of 23 self-report items, with each item scored using a standardized quantitative response scale that allows the calculation of an overall Acculturation Score. Individual responses are summed to produce a total score reflecting the participant’s overall level of cultural adaptation, integration into the host society, and adjustment to everyday life in Greece.

Higher scores indicate greater acculturation, stronger Greek language proficiency, higher levels of social participation, greater integration into the cultural and social environment of the host country, stronger interpersonal functioning, and better psychological adjustment. Lower scores indicate more limited cultural adaptation, reduced linguistic competence, lower levels of social integration, and an increased likelihood of experiencing acculturative stress, social isolation, or adjustment difficulties.

Interpretation of questionnaire scores should always be supported by comprehensive psychometric evaluation, including analyses of Cronbach’s alpha coefficients, construct validity, criterion validity, exploratory and confirmatory factor analyses, measurement invariance, normative comparisons, and cross-cultural validation, ensuring reliable assessment across diverse immigrant populations and cultural contexts.
