The Ways of Coping Questionnaire (WCQ): The Standard in the Field. Already in the 1970s, the stress and coping research group of Lazarus developed the Ways of Coping Checklist (WCC) in line with the transactional phenomenological stress theory that suggested two main functions of coping: problem solving and emotion regulation (cf. Lazarus, 1991).

Abstract
The Ways of Coping Questionnaire (WCQ) is a widely used measure of coping processes. Despite its use in a variety of populations, there has been concern about the stability and structure of the WCQ across different populations. This study examines the factor structure of the WCQ in a large sample of individuals diagnosed with fibromyalgia. The participants were 501 adults (478 women) who were part of a larger intervention study. Participants completed the WCQ at their 6-month assessment. Foundational factoring approaches were performed on the data (i.e., maximum likelihood factoring [MLF], iterative principal factoring [IPF], principal axis factoring (PAF), and principal components factoring [PCF]) with oblique oblimin rotation. Various criteria were evaluated to determine the number of factors to be extracted, including Kaiser’s rule, Scree plot visual analysis, 5 and 10% unique variance explained, 70 and 80% communal variance explained, and Horn’s parallel analysis (PA). It was concluded that the 4-factor PAF solution was the preferable solution, based on PA extraction and the fact that this solution minimizes nonvocality and multivocality. The present study highlights the need for more research focused on defining the limits of the WCQ and the degree to which population-specific and context-specific subscale adjustments are needed.
1. Factor Structure of the Ways of Coping Questionnaire in a Large, Clinical Sample of Fibromyalgia PatientsCoping Strategy Questionnaire
The Ways of Coping Questionnaire (WCQ) has been a widely used measure of coping processes for the last three decades [1, 2]. The questionnaire was designed to identify the thoughts and actions that individuals use to cope with stress and to discern patterns of coping within specific contexts [3–5]. It has been used to assess coping in response to unique situational stressors, as well as to examine coping within different cultural, occupational, and clinical populations. Despite its use in a variety of populations, including populations with chronic health concerns [3, 6–8], there is no examination of its structure in a sample of individuals with fibromyalgia syndrome (FMS).

1.1. The WCQ and Coping
The WCQ is based on the original 68-item Ways of Coping Checklist (WCC), which has a “yes” or “no” response format [9, 10]. The addition of a 4-point Likert response format and the revision of a few of the items to improve clarity were the primary adjustments made in creating the final 66-item version of the WCQ. The use of the WCQ within different populations and across multifarious situational stressors has made evident the complexity and dynamism of the process of coping and attempts to measure this process rigorously [2, 7, 8]. Perhaps the quintessential modern-day approach for assessing the structure of a measure at present is factor analysis [11, 12]. However, factor analyses of the WCQ within and across particular sample types have identified disparate solutions—both in structure and in content—compared to the original 8-factor solution derived by Folkman and Lazarus [10]. These findings may reveal what the genuinely unique coping strategies and structures within different populations and situations are, which may imply that the WCQ should be revised and made population-specific [8].
1.2. Original Factor Solution of WCQWays Of Coping Questionnaire Free
The sample used to obtain the “original” 8-factor solution for the WCQ was comprised of students undergoing examination stress [10]. They used common factor analyses with oblique rotation and found six factors in a sample of undergraduates. Stress and coping were measured at three different time points across the examination process. One of the emotion-focused factors loaded was “rationally” divided into three groups “to provide greater theoretical clarity” ([10], p. 157). After this rational division, eight factors were extracted, and this 8-factor solution was “replicated” in the community sample of 150 married adults [4, 5]. Importantly, Folkman and Lazarus noted neither which specific factor analytic strategies were used nor which factor was divided after solution.
1.3. Attempts to Replicate Original Study in Student SamplesWays Of Coping Scale Pdf
In a derivative study that measured coping in undergraduate students who were presented vignettes of stressful encounters, only five of the eight factors were replicated [7]. It is noteworthy that although this solution yielded fewer factors than the authors’ studies [4, 5], the eigenvalue > 1 rule has been reported to consistently extract too many factors ([13–17]; for a summary, see [11]). The five factors were similar in content to the originally identified domains (see Table 1 for a synopsis of study characteristics). Scherer et al. [7] also did not divide a mathematically extracted factor into three, distinct, “rationally derived” factors. In addition, the stressors presented in the study were hypothetical as opposed to the real stressors measured in the Folkman and Lazarus [10], Folkman et al. [5], and Folkman et al. [4] studies, although these methodological differences may account for the variability in the factors extracted between these studies. Parker et al. [6] measured coping in undergraduate students two days prior to taking their midterm exam (corresponding to Folkman and Lazarus [10]) and failed to find support for the six- and eight-factor oblique and orthogonal models suggested by the student sample [10] and the community sample [4, 5]. These studies started a long history of inconsistency in the structural composition of the WCQ identified via factoring or other dimension reduction techniques (e.g., principal components analysis [PCA]).
