Abstract

Background

Research on dysmorphic concerns (DC) in Arabic-speaking contexts is hampered by the lack of validated tools. Because DC are culturally dependent, psychometrically sound measures are needed at the national level to closely and accurately investigate the construct in specific societies and populations. The purpose of the current research was to investigate the psychometric properties of Dysmorphic Concern Questionnaire (DCQ) in its Arabic translation in Lebanese adults.

Methods

The study involved 515 participants (69.9% females, mean age of 27.55 ± 10.92 years) who completed a self-report, web-based questionnaire.

Results

Confirmatory factor analysis indicated excellent construct validity, as the one-factor structure of the Arabic DCQ fits well with the data. McDonald’s omega was 0.89 in our sample, evidencing an excellent level of internal consistency. Furthermore, the results from the multigroup analysis showed that the DCQ holds similar structural model between genders at the metric, configural, and scalar levels. Finally, DC levels correlated inversely with body appreciation and self-esteem and positively with disordered eating symptoms, thus supporting the concurrent and convergent validity of the Arabic DCQ.

Conclusion

The DCQ translated into Arabic appears to have a valid self-assessment measure to capture the presence of DC manifestations. It is anticipated that the Arabic DCQ will be advantageous for healthcare professionals and researchers working with Arabic-speaking people around the world.

Introduction

Dysmorphic concerns (DC) refer to excessive preoccupations with certain imagined or barely perceptible physical appearance defects [1,2,3], which are either specific (e.g., acne, large nose, balding) or vague reflecting a general view of ugliness. These preoccupations are experienced as intrusive, are hard to control, and difficult to resist [4]. The DC construct also involves subsequent behaviors directed at controlling the defect(s), social avoidance [3], significant distress, and/or impaired functioning [5]. Body dysmorphic symptoms are distributed along a continuum throughout the general population, with symptoms not differing qualitatively at varying levels of severity [6]. Therefore, DC may reflect a proneness to development of diagnosable body dysmorphic disorder (BDD) or indicate a relevant diagnosis of subclinical or clinical BDD [7, 8].

Beyond a greater risk for developing BDD, subthreshold body dysmorphic symptoms were associated with reduced quality of life [9, 10] and higher degrees of coexisting psychiatric conditions (major depressive disorder [11], obsessive compulsive disorder [12, 13], social anxiety [14], compulsive sexual behavior [15], eating disorders [16], and substance use disorder [17]). DC are also associated with a high desire for cosmetic surgery, which may, in turn, confer a risk of addiction to surgery and subsequent adverse events [18] and was proven not effective in relieving symptoms [19]. Besides, people with DC were shown to often experience general and body shame [20], decreased self-esteem [21], and increased odds for suicide thoughts and attempts [22]. DC are more likely to emerge during adolescence [23]. They seem to affect an estimated 0.7 to 3.2% of the general public [24, 25], 2.3 to 5.8% of university students [26, 27], and 6.9 to 17.2% of plastic surgery and dermatological outpatients [28, 29]. However, these prevalence rates are likely underestimated because most patients do not seek help or do so only when they are at advanced stages of the disease [30]. Given the high prevalence estimates of DC and their subsequent harmful concerns on physical and mental wellbeing, investigating the psychometric properties of measurement instruments, which intend to evaluate the DC construct, is warranted.

Multiple measurement tools were developed to capture DC symptoms and are used either as screening tools or for clinical diagnostics. There are semi-structured, clinician-administered measures that are recommended for clinical assessment of BC, such as the BDD Diagnostic Module for DSM-5 (BDDDM) [31], the 34-item semi-structured clinical interview Body Dysmorphic Disorder Examination [32], and the Yale-Brown Obsessive–Compulsive Scale, modified for BDD (BDD-YBOCS; [33]). These measures offer the advantage of obtaining accurate ratings and being practical for treatment outcomes, as they allow for a detailed evaluation of typical symptoms that can be treatment targets. However, they may be less convenient as screening measures as they are too time-consuming. Moreover, they do not enable the detection of comprehensive information (e.g., specific symptoms, such as cognitions) related to DC [34]. Acknowledging the gaps in screening for DC, Mancuso et al. [35] designed and validated the Dysmorphic Concern Questionnaire (DCQ), a 7-item self-report tool intended for screening BDD.

The DCQ is a 7-item measure scored on a 4-point scale, aiming to assess concerns related to physical appearance as a potential symptom, eliminating the necessity to diagnose BDD [35]. Therefore, the DCQ enables assessing subclinical and clinical DC, without prejudging the pathology and etiology of the disorder [36]. The DCQ was found to have a single-factor structure and an appropriate internal consistency (Cronbach’s alpha of 0.88). The scale also showed good validity, as attested by adequate patterns of correlations with distress, social impairment, and work [2]. Due to its relative shortness, simplicity, and low cost, the DCQ was widely used for clinical purposes and in large epidemiological studies [35, 37]. In addition, several psychometric studies demonstrated the adequate reliability and validity of the DCQ in various countries and languages, including Persian [38], Spanish [8], Greek [39], and German [40]. The DCQ was also subject to validation in different populations and contexts, such as university students [38], nonclinical adolescents and young adults [41], UK adult twins [42], sexual minority adults [43], psychiatric inpatients [36], dermatological outpatients [44], and individuals suffering from BDD [39]. All these studies further confirmed the psychometric robustness of the instrument in terms of internal consistency and validity. However, no translation or validation of the DCQ is available for Arabic-speaking populations to date to our knowledge [45].

The present study

The way individuals perceive and deal with their body areas of concern and body image in BDD are largely determined by sociocultural norms [46]. Historically, thinness was considered undesirable in the Arabic culture and societies, which rather give preference to plump bodies as symbol of femininity. However, under the influence of modernization and westernization, Arab countries have known gradual changes in beauty ideals, with continuously rising levels of dissatisfaction and concerns about body shape or image [47]. For instance, a previous study indicated that prevalence estimates of BDD in Arab people from the general population of Saudi Arabia (8.8%) were higher than those reported in international studies from Western countries, a finding that was partly explained by social and cultural factors [48]. It is of note, however, that authors used a screening measure, i.e., the Body Dysmorphic Disorder Questionnaire (BDDQ, [49]), in its Arabic-translated version without testing its psychometric properties [48]. This points to the fact that research on DC in Arabic-speaking contexts is hampered by the lack of validated tools. Because DC are culturally dependent, psychometrically sound measures are needed at the national level to closely and accurately investigate the construct in specific societies and populations. In this study, we aimed to investigate the psychometric properties of the DCQ in its Arabic translation in Lebanese adults. We postulated the following hypotheses regarding the Arabic DCQ: (1) it will exhibit strong uni-structural validity, (2) it will demonstrate reliable internal consistency, (3) its structure will remain invariant between genders, and (4) it will show satisfactory convergent and concurrent validity as indicated by substantial relationships with assessments of disordered eating, body appreciation, and self-esteem.

Methods

Procedures

Between February and March 2023, data for this cross-sectional study was collected through a Google Form link. The research team invited people to complete the survey; those who agreed were requested to share the link with others, following the snowball sampling technique. Inclusion criteria comprised being an adult who resides in and is a citizen of Lebanon. Exclusions encompassed individuals declining to complete the questionnaire. The survey was conducted anonymously, and participation was voluntary and without compensation [50].

Translation procedure

Prior to utilization in the current study, the DCQ scale underwent translation for adaptation for the Arabic language and cultural context. The translation aimed to attain semantic equivalence between the original measures and their Arabic counterparts, adhering to international recommendations [51]. A Lebanese translator, unaffiliated with the study, independently translated the English version into Arabic. Following that, a Lebanese psychologist, proficient in English, translated the Arabic version back into English. To ensure accuracy, a committee of experts, comprising two psychiatrists, one psychologist, and the research team, compared the original and translated English versions, identifying and correcting any inconsistencies [52]. Following this, a pilot study involving 30 patients was conducted to validate the clarity of all questions. No modifications were made after the completion of the pilot study.

Measures

Dysmorphic Concern Questionnaire (DCQ)

The DCQ is composed of seven items assessing concerns about and belief in physical appearance (e.g., “Have you ever been very concerned about some aspect of your physical appearance?” or “Have you ever spent a lot of time covering up defects in your appearance/bodily functioning?”) [2]. Participants rate seven items on a 4-point scale, with higher values indicating greater DC.

Eating Attitude Test (EAT-7)

The condensed version of the EAT-26 [53, 54] comprises seven items, each assessed on a 6-point Likert scale [55]. Elevated scores indicate more pronounced symptoms of disordered eating (ω = 0.84).

Body Appreciation Scale (BAS-2)

Validated in Arabic [56, 57], it comprises 10 items measured on a 5-point scale, extending from “never to always” [58]. Higher levels point to higher levels of body appreciation (ω = 0.96).

The Single‑Item Self‑Esteem scale (SISE)

Validated in Arabic [59], it is composed of one item (i.e., “I have high self-esteem”) [60], measured on a 5-point Likert scale from “not at all true of me to very true of me.” Higher scores reflect higher levels of self-esteem.

Analytic strategy

Confirmatory factor analysis (CFA)

The dataset contained no missing responses. Utilizing data from the entire sample, we conducted a CFA using SPSS AMOS v.29 software. Our sample size exceeded the minimum requirement of 140 participants, considering a ratio of 20 participants per scale item for conducting a CFA [61]. Our objective was to assess the original one-factor model of the DCQ. Parameter estimates were obtained through the maximum likelihood method, and model fit was evaluated using various indices, including the normed model chi-square (χ2/df), the Steiger-Lind root-mean-square error of approximation (RMSEA), the Tucker-Lewis index (TLI), and the comparative fit index (CFI). Adequate fit was indicated by values ≤ 5 for χ2/df, ≤ 0.08 for RMSEA, and ≥ 0.90 for CFI and TLI [62]. Additionally, convergent validity was examined through average variance extracted (AVE) values, with ≥ 0.50 considered satisfactory [63]. Multivariate normality was not established (Bollen-Stine bootstrap p = 0.026), prompting the use of nonparametric bootstrapping procedure.

For the examination of gender invariance in DCQ scores, a multigroup CFA was conducted on the total sample [64], assessing configural, metric, and scalar levels of measurement invariance [65]. Invariance was acknowledged with ΔCFI ≤ 0.010, ΔRMSEA ≤ 0.015, or ΔSRMR ≤ 0.010 [50].

Further analyses included assessing composite reliability using McDonald’s ω, with values greater than 0.70 considered acceptable [66]. Normality was confirmed as skewness, and kurtosis values ranged between − 1 and + 1 [67]. Pearson test was employed for correlations of scores and Student t-test for means comparison.

Results

Participants

A total of 515 individuals participated in this study (69.9% females, mean age: 27.55 ± 10.92 years, and 83.7% with a university level of education).

Confirmatory factor analysis of the DCQ scale

CFA showed that fit of the one-factor structure of the DCQ scale was acceptable: χ2/df = 48.37/14 = 3.46, RMSEA = 0.069 (90% CI 0.048, 0.091), SRMR = 0.027, CFI = 0.980, and TLI = 0.970. The standardized estimates of factor loadings were all adequate (Fig. 1). The convergent validity for this model was borderline, as AVE = 0.73 (ω = 0.89).

Gender invariance

The invariance across gender of the DCQ at the metric, configural, and scalar levels was demonstrated (Table 1). There is no statistically significant difference between men and women regarding DCQ scores (5.86 ± 5.14 vs 6.63 ± 5.10; t =  − 1.549; p = 0.122).

Convergent and concurrent validity

Elevated DCQ scores demonstrated a significant correlation with higher EAT scores, indicating a greater level of disordered eating (r = 0.15) and lower body appreciation (r =  − 0.43) and reduced self-esteem (r =  − 0.18) (Table 2).

Discussion

Despite its high prevalence and negative health effects, DC remain under-researched and poorly understood worldwide [68]. It is therefore no surprise that Arab people are largely under-represented in the literature on DC. Thus, there appears a clear need for clinically useful, psychometrically acceptable, and easy to apply measures to assess DC among Arabic-speaking populations. In an effort to contribute to the progression of the field, our aim was to validate the DCQ into Arabic. The present results indicate that the one-factor model of the DCQ was reproduced in our nonclinical adult sample for both males and females. The scale showed adequate internal consistency (McDonalds’ omega of 0.89), as well as good convergent validity. In general, these findings imply that the Arabic DCQ is appropriate for use as a screening tool to detect Arabic-speaking individuals with excessive dysmorphic concerns, who could be at risk of developing BDD.

CFA indicated excellent construct validity, as the single-factor model of the Arabic DCQ showed a good fit to the data. This suggests that all seven items assess the same construct. Consistent with our results, previous findings using CFA and principal component analysis have indicated a unidimensional solution in various populations and contexts, including German community adults [40], UK adult twins [42], Australian community youth aged 12–21 years [41], Australian psychiatric patients [2], Iranian university students [38], multiethnic sexual minority individuals residing in the USA [43], Spanish university students and nonuniversity general population [8], and Greek adults with BDD and healthy controls [39]. Collectively, these results affirm the cross-cultural validity of the one-factor model of the DCQ. The benefit of the latter lies in its ease of calculating a total score, making it conducive for use in screening studies.

McDonald’s omega was 0.89 in our sample, evidencing an excellent level of internal consistency. Similarly, the various linguistic versions of the DCQ available showed adequate internal consistency values, including the English (Cronbach’s α ranging from 0.80 to 0.88) [2, 36, 41,42,43], Persian (α = 0.78) [38], Spanish (α = 0.85) [8], German (α = 0.81) [40], and Greek (α = 0.933) [39] versions. Furthermore, and as expected, the results from the multigroup analysis found that the DCQ in its Arabic version holds similar factor structure between gender groups at the metric, configural, and scalar levels. This suggests that Arab male and female respondents ascribed the same meaning to DCQ items, thus implying that the latent means can be compared across gender. Although several previous studies have assessed the psychometric qualities of the DCQ within both clinical and nonclinical populations, there is surprisingly little information available on invariance properties of DCQ scores, thereby limiting its potential use for gender comparisons. We could find only one study that provided support to the invariance of the DCQ across gender in sexual minority individuals [43]. Accordingly, we draw the attention of researchers to the need to establish cross-gender measurement equivalence before exploring any potential differences in group means [69]. In the current sample, there was no statistically significant difference observed between Arab females and males in terms of DCQ latent mean scores. Prior research pointed to substantial differences in major symptom phenomenology across gender in adults with BDD [70]. For instance, females seem to be more preoccupied by their breasts and thighs and more likely to exhibit BDD-related behaviors, while males seem to be more concerned with their muscularity and more likely to report high BDD-related disability [70,71,72]. Although there may be symptom-based gender differences, there are also similarities in the frequency and severity of appearance concerns between genders [71, 72], which is broadly in line with our findings.

Finally, the hypothesized patterns of correlations between DC scores and other relevant measures were confirmed, supporting the concurrent and convergent validity of the Arabic language DCQ. In particular, DC levels correlated inversely with body appreciation and self-esteem and positively with disordered eating symptoms. In agreement with these findings, there is solid research suggesting that preoccupation for perceived physical defect(s) and related behaviors is predictive of disordered eating [73, 74] and low self-esteem [21]. Additionally, body image disturbance represents a hallmark characteristic of DC [75]. These observations further highlight the usefulness of DCQ as a measure of DC symptoms’ severity and its clinical relevance in a series of health problems. Therefore, the translated Arabic measure can be considered suitable for specific assessment of the phenotypic continuum of DC across the general population and, therefore, identification of individuals at risk of developing BDD. However, we caution readers that the DCQ does not allow for establishing a final BDD diagnosis, and that a structured diagnostic interview is still required to confirm the existence of a diagnosable disorder.

Study limitations and research perspectives

The adoption of self-report measures and convenience web-based sampling method may introduce response bias and limit the representativeness of the study’s sample. Our participants consisted of nonclinical Arabic-speaking adults from one Arab country (i.e., Lebanon); consequently, our findings may not be applicable to other Arab countries. Future validation studies are needed to verify the scale’s vigor in clinical populations (e.g., patients with BDD, patients undergoing plastic surgery, or other cosmetic procedures) and across other Arab settings (e.g., Gulf or North African countries). Finally, some essential psychometric properties (e.g., test–retest reliability) were not studied in this work.

Conclusion

Our addition to the current body of literature lies in expanding the understanding of the psychometric qualities of the DCQ in a new language and context. Results suggest that the DCQ in its Arabic translated and validated version may serve as a reliable self-report screening tool for capturing manifestations of DC. In addition, our study stands among pioneers in confirming measurement invariance of this scale across gender, which can help inform future studies aiming at investigating differences in levels of DC between males and females in Arab contexts. As the BCQ has been validated and used in many countries throughout the world, making its Arabic version available will allow for accurate cross-national comparison on DC to be made. We hope that the Arabic validated version of the DCQ will benefit clinicians and researchers working with Arabic-speaking populations in different parts of the world.
