Abstract

Recently, the research on pain-related disability has increasingly paid attention to the psychological and social factors that may influence the biological condition. In the current study, we aimed to explore attachment styles, self-esteem, and quality of life in individuals with a diagnosis of fibromyalgia. Participants were 371 diagnosed women, with a mean age of 42.7 years (standard deviation = 10.6). The average number of years since diagnosis was 7.4 years (standard deviation = 2.4) years. To assess attachment, quality of life, and self-esteem, women responded, respectively, to the Relationship Questionnaire, the World Health Organization Quality of Life Questionnaire, and the Rosenberg Self-Esteem Inventory. Our results showed that secure attachment relationships and high self-esteem represent protective factors for quality of life of women with fibromyalgia, while the contrary emerged for insecure attachments and low self-esteem. The understanding of the psychological components that contribute to fibromyalgia may improve the effectiveness of interventions.

Fibromyalgia (FM) is a chronic widespread pain disorder that predominantly affects women (Legand et al., 2019; Rudin, 2019; Tavares et al., 2020). Due to the musculoskeletal pain, FM can result in quality of life (QoL) deterioration and impairment (Walker and Littlejohn, 2006). Indeed, this rheumatic illness is characterized by not only fatigue and pain but also difficulties with daily living movements, going from basic tasks to more complex responsibilities such as work and social relationships (Verbrugge and Juarez, 2006).

Previous studies on the consequences of rheumatic disorders emphasized the medical and biological perspective (Walker and Littlejohn, 2006). However, more recently, researchers tried to recognize the roles of social, demographic, physiological, and psychological factors with respect to chronic physical illness (Verbrugge and Juarez, 2006). In this regard, the World Health Organization (WHO) supported the International Classification of Functioning (ICF), incorporating a more complete bio-psycho-social framework of disability, health, and health-related conditions (WHO). Consequently, the ICF takes a neutral position about etiology and permits scholars to achieve causal inferences through suitable scientific methods, trying to remove conventions that biological dysfunction is the critical viewpoint of QoL (Cieza et al., 2004).

This approach is determinant since FM’s etiology and development are still unidentified, and high comorbidity and heterogeneity increase difficulties in studying FM (Chamie, 1995; Su et al., 2015).

Undeniably, FM is a complex bio-psycho-social condition influenced by several psychological aspects, such as fear relating to pain, beliefs about pain, self-esteem, anxiety, depression, lack of social support, affect differentiation, resilience, coping strategies, and emotion regulation (Dima et al., 2013; Tunks et al., 2008), that may even result in an increased risk for suicidality (Amir et al., 2000; Dreyer et al., 2010), a cross-cutting concern of mental problems (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5), American Psychiatric Association (APA), 2013).

Thus, to mitigate the negative consequences of FM on the person’s functioning, it is crucial to acknowledge the psychological factors that may be implicated.

Adult attachment styles

Empirical studies suggest that adult attachment styles are linked to pain-related disabilities (MacDonald and Kingsbury, 2006; Meredith et al., 2006).

Attachment investigators have recognized four attachment styles that differ along two dimensions: attachment anxiety (degree to which individuals worry about being unvalued or rejected by significant others) and attachment avoidance (the degree to which persons are at ease with affective closeness in significant relationships). Securely attached individuals are low on both dimensions, preoccupied individuals are high in anxiety and low in avoidance, dismissing persons are high in avoidance but low in anxiety, and fearful persons are high on both (Collins and Read, 1990). Moreover, secure persons have a positive model of both self and others; those with a fearful attachment have a negative image of both self and others. Preoccupied persons have a negative image of self and a positive image of others, and those with a dismissive attachment have a positive image of self and a negative image of others (Bartholomew and Horowitz, 1991; Griffin and Bartholomew, 1994).

It has been proved that about 65 percent of people in normative samples are securely attached, whereas 35 percent are insecurely attached (Mickelson et al., 1997); in chronic pain patients, these percentages seem to be reversed (Kowal et al., 2015; Meredith, 2016).

Some studies showed that attachment anxiety is related to a negative perception of one’s pain-coping capacity, lower somatic pain levels, and decreased experiences of control over pain (Sullivan et al., 2001). Individuals with anxious or avoidant attachment have been found to report greater levels of negative pain beliefs (McWilliams and Asmundson, 2007). Also, other studies showed that chronic insecurely attached pain patients reported significantly higher levels of pain intensity as well as pain-related suffering and less pain self-efficacy than chronic securely attached pain patients (MacDonald and Kingsbury, 2006; Meredith et al., 2006).

In the context of FM, it has been documented that individuals with insecure attachment styles are exceptionally represented (Hallberg and Carlsson, 1998). In particular, Peñacoba et al. (2017) revealed that women with a diagnosis of FM presented lower rates of secure attachment style (69.9% vs 86%), higher avoidant (19.8% vs 7.4%), and anxious–ambivalent attachment (10.3% vs 6.6%) compared to healthy women.

QoL in FM

Women with a diagnosis of FM report several clinical problems, such as tiredness, sleep perturbations, stiffness, skin sensitivity, irritable bowel syndrome, cognitive disturbance, headaches, fluid retention, paresthesia, restless legs, and anxiety/depressive symptoms. These enduring physical and psychological manifestations may affect the patients’ QoL (Galvez-Sánchez et al., 2019; Verbunt et al., 2008). Compared to other patients with a chronic disease (e.g. osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, myocardial infarction, chronic obstructive pulmonary disease, congestive heart failure, hypertension, and diabetes), FM patients refer the poorer health condition (see Lee et al., 2017).

Internationally, numerous studies have confirmed the effect of several factors on the QoL of women with a diagnosis of FM. Among these variables, the most relevant are age, educational level, number of children, comorbidity with a rheumatologic diseases (Linares et al., 2008), employment status (Reisine et al., 2004), depression, anxiety, self-efficacy, and social support (Alok et al., 2014; Lee et al., 2017; Pagano et al., 2004; Tander et al., 2008).

However, it is important to underline that both objective and subjective factors that refer to general satisfaction with life or its components must be considered in understanding the impact of FM on the reported QoL (Bowling et al., 2002). In particular, the relationships between adult attachment styles and QoL in FM patients still need to be investigated. Also, according to attachment theory (Bowlby, 1977), the link between attachment and QoL may be mediated by several pathways, one of which is self-esteem (Brennan and Bosson, 1998).

Self-esteem

Self-esteem plays a crucial role in the QoL of FM patients, influencing disease complications (Galvez-Sánchez et al., 2019).

Self-esteem is

the degree to which the qualities and characteristics contained in one’s self- are perceived to be positive. It reflects a person’s physical self-image, view of his or her accomplishments and capabilities, and values and perceived success in living up to them, as well as the ways in which others view and respond to that person. (Granito, 2007)

It has been demonstrated that there is a major decrease in self-esteem and self-efficacy in FM patients (Galvez-Sánchez et al., 2018). Poor self-esteem may consequently influence overall FM patients’ impairment. For this reason, it is important to be evaluated.

Significant research indicates that insecure attachment is related to lower self-esteem in comparison with secure attachment styles (Collins and Read, 1990; Foster et al., 2007). Consequently, FM patients with insecure attachment style may be prone to low self-esteem, which in turn may result in reduction of QoL (Galvez-Sánchez et al., 2019).

Therefore, the present study was conducted with the aim of improving current knowledge and understanding of attachment styles and their connection with self-esteem and QoL in individuals with a diagnosis of FM. Specifically, we hypothesized a significant link between insecure attachment styles, low self-esteem, and poor QoL. In particular, according to Bartholomew and Horowitz’s adult attachment model (1991), it was postulated that preoccupied and fearful attachment styles would be associated with lower self-esteem and poorer QoL.

Method

Participants

Participants were 371 women with a physician’s diagnosis of FM. The age of the participants ranged from 27 to 62 years, with a mean age of 42.7 years (standard deviation (SD) = 10.6). The average number of years since diagnosis was 7.4 years (SD = 2.4).

Most participants were married (80.3%), 10.8 percent were separated, 7.8 percent were single, and 1.1 percent were widowed. In terms of education level, most of our sample had a high school diploma (48.8%), followed by 39.7 percent who completed a university degree and 11.5 percent, a doctorate or post-doctorate degree. The sample was composed solely of Italian Caucasian women. No incentives were given to the study participants. The sampling was non-probabilistic and involved women who voluntarily participated in the research.

Measures

Adult attachment styles

The Relationship Questionnaire (RQ; Bartholomew and Horowitz, 1991) was used to assess adult attachment styles. The RQ comprises four different paragraphs describing the secure, dismissing, preoccupied, and fearful attachment styles. Participants evaluated themselves on each of the four attachment styles using a scale ranging from 1 (disagree strongly) to 7 (agree strongly). The RQ as a measure of adult attachment has been commonly used and has shown satisfactory validity as measured with concurrent self- and friend-reports of interpersonal functioning (Bartholomew and Horowitz, 1991), as well as longitudinal observer-based assessments of personality and behavioral characteristics (Klohnen and Bera, 1998).

QoL

The World Health Organization Quality of Life Questionnaire (WHOQOL-BREF; World Health Organization, 2011; Italian version, Girolamo et al., 2000) was used to assess the QoL. The scale consisted of 26-items rated on a 5-point Likert-type scale (from 1 = not at all to 5 = completely). The WHOQOL-BREF assesses QoL in four areas: physical health (PHY, 7 items), psychological health (PSY, 6 items), social relationships (SR, 3 items), and environment (EN, 8 items). Two of the items provide a component quantifying Overall QoL/health. The WHOQOL-BREF has been utilized to evaluate QoL in individuals with many diseases as chronic fatigue syndrome (Van Heck and Vries, 2002). Higher scores show a higher perceived QoL. Data from many states showed good internal consistency reliability and construct validity for the international WHOQOL-BREF (Skevington et al., 2004).

Self-esteem

The Rosenberg Self-Esteem Inventory (RSEI, Rosenberg, 1965; Italian version by Prezza et al., 1997) was used to assess global self-esteem. The scale consisted of 10-items rated on a 4-point Likert-type scale (from 1 = strongly agree to 4 = strongly disagree). The participants responded to items about their positive (e.g. I feel that I have a number of good qualities) and negative (e.g. I certainly feel useless at times) feelings about the self. Higher scores show a higher global self-esteem. The RSEI has generally demonstrated good psychometric properties (Curbow and Somerfield, 1991).

Recruitment and procedure

Participants were recruited from online sources. We posted announcements on FM online communities. The statement specified that we were carrying out “a research on women with a diagnosis of FM.” To participate, the women were required to be at least 18 years old and had previously received a certified diagnosis of FM. The ad then offered a linkage to the anonymous online survey. After giving consent, the women completed the next three pages of the survey, which included items to evaluate the above screening criteria. Women who were eligible were permitted to continue the study. Women who did not meet the eligibility conditions were thanked for their time. All applicants were informed about their rights as a study participant and participation was anonymous.

Data analyses

Statistical analysis was done with SPSS and Amos 21. The data were preliminarily screened for errors and outliers. Multiple imputation (MI; Galbraith, 2012) was applied to operate missing data. Prior to execution of MI, the data were evaluated to verify that absent values were missing at random (MAR). Subsequently, the level of missing data was analyzed to assure that less than 10 percent of data were lacking across scale scores. The assumption of MAR was met, and the percentage of missing data across scales (2%–4%) was appropriate. Twenty-five multiply imputed data sets were generated.

We explored the distribution of all study variables. Descriptive and correlation analysis were performed. Subsequent to conducting correlations among the study variables, tests of mediation were performed through a structural equation model (SEM). Four models were tested to examine self-esteem as a potential mediator of the relation between attachment style and QoL. Each model comprised one hypothetical observed independent factor (attachment style), one observed mediator factor (self-esteem), and one latent dependent factor (QoL). The QoL latent factor was measured using the four subscales of the WHOQOL-BREF (PHY, PSY, SR, and EN).

To evaluate the hypothesized model, numerous indicators were taken into consideration (Kline, 2015). Since the χ² statistic is susceptible to sample size, other fit indicators have been measured: the comparative fit index (CFI), the Tucker–Lewis index (TLI), the standardized root mean square residual (SRMR), and the root mean square error of approximation (RMSEA), along with its 90 percent confidence interval (CI). It is suggested that good fit indicators for CFI and TLI are greater than .90, and for SRMR and RMSEA, less than .08 (Markus, 2012). A bootstrapping procedure using 1500 subsamples was done to assess the statistical significance of each path coefficient.

Results

Preliminary analyses

Descriptive statistics (mean and SD) and correlations for all model variables are presented in Table 1. At the bivariate level, supporting hypotheses, secure attachment style was correlated with high self-esteem as well as with high physical, psychological, social, and environmental health. Conversely, dismissing, preoccupied, and fearful attachment styles were associated with low self-esteem as well as with low physical, psychological, social, and environmental health. Finally, high self-esteem levels were associated with high physical, psychological, social, and environmental health.

Tests of mediation

Four structural models were used to assess the effect of each attachment style and self-esteem on QoL.

Specifically, the models estimated the direct effect of each attachment style (Models A, B, C, and D) on self-esteem, the direct and indirect effects of each attachment style on QoL, and the direct effect of self-esteem on QoL. Table 2 illustrates the indirect effects of self-esteem on the associations between each attachment style and QoL. Figure 1 graphically shows the relationship for each of the attachment styles, self-esteem, and QoL.

Path models.

Model A (secure attachment style)

The results of the path model were good (χ² = 18.33, df = 8, p = .02, CFI = .98, incremental fit index (IFI) = .98, RMSEA = .06 (90% CI = .02, .09), SRMR = .03). Secure attachment style had significant direct effect on self-esteem as well as direct and indirect effects on QoL. Also, self-esteem had statistically significant direct effect on QoL.

These results showed that women’ attachment secure style affected both directly and indirectly, through self-esteem, QoL.

Model B (dismissing attachment style)

The results of the path model were appropriate (χ² = 16.66, df = 8, p = .03, CFI = .98, IFI = .98, RMSEA = .05(90% CI = .01, .09), SRMR = .03). Dismissing attachment style had significant direct and indirect effects on QoL. Dismissing attachment style had significant direct effect on self-esteem and self-esteem had statistically significant direct effect on QoL. These results showed that women’ attachment dismissing style affected both directly and indirectly, through self-esteem, QoL.

Model C (preoccupied attachment style)

The results of the path model were very good (χ² = 11.98, df = 8, p = .15, CFI = .99, IFI = .99, RMSEA = .04 (90% CI = .00, .08), SRMR = .03). Preoccupied attachment style had significant direct and indirect effects on QoL. Preoccupied attachment style had significant direct effect on self-esteem and self-esteem had statistically significant direct effect on QoL. These results showed that women’ attachment preoccupied style affected both directly and indirectly, through self-esteem, QoL.

Model D (fearful attachment style)

The results of the path model were good (χ² = 16.93, df = 8, p = .03, CFI = .98, IFI = .98, RMSEA = .06 (90% CI = .02, .09), SRMR = .03). It should be observed that there was no significant direct effect of fearful attachment style on QoL. Fearful attachment style had only significant indirect effect on QoL. Fearful attachment style had significant direct effect on self-esteem and self-esteem had statistically significant direct effect on QoL. These results showed that women’ attachment fearful style affected indirectly, through self-esteem, QoL. Women with FM with fearful attachment levels are prone to lower self-esteem which may, in turn, lower their QoL.

Discussion

Our findings support the notion that psychological characteristics are critical in understanding FM pathology. Improving knowledge of variables that either aggravate or impede coping with chronic pain conditions, such as FM, is a crucial interest of health psychology.

The QoL relies on the aspects of physical, psychological, environments, and social wellbeing. These features are linked to self-esteem that is compromised due to the social impairment connected to having a chronic disease (Brorsson et al., 2001).

Some empirical studies have documented the relationship between attachment style and physical and psychological symptoms reported by FM patients (MacDonald and Kingsbury, 2006; Meredith et al., 2006). However, to our knowledge, this is the first study to evaluate whether self-esteem mediates the relationship between attachment style and QoL in a sample of women with a diagnosis of FM.

Low self-esteem, in chronic illness, has a negative effect on women’ interpersonal relations, feelings, and emotions. In FM patients, several research studies have proved that self-esteem is considerably lower compared to healthy persons (Galvez-Sánchez et al., 2018; Garaigordobil, 2015).

Women suffering from FM, due to the feeling of loss of self-control, are predisposed to low self-esteem, which in turn will result in reduction of QoL and increase in prevalence of mental problems and physical illnesses. In line with attachment theory, secure attachment relationships may promote positive feelings of self-worth (Allen, 2018).

In our study, it was found that there was a significantly different effect on levels of self-esteem between women with secure and insecure attachment style. Secure attachment style was found to be related to higher levels of self-esteem, while insecure attachment style was found to be linked with lower self-esteem levels.

In support of our hypotheses and in accordance with Bartholomew and Horowitz (1991), our results showed that self-esteem is an important issue, linking attachment styles and QoL in women with FM.

Secure, dismissing, and preoccupied attachment styles were also directly associated with QoL, as secure/insecure attachment may lead to the success or failure of protective factors for health.

It is plausible that securely attached FM patients define themselves, perceive others in more positive terms, and react to pain with less distress, spending more time thinking of positive aspects of their life. Conversely, insecurely attached women with a diagnosis of FM may perceive themselves and others in more negative terms and react to pain with more suffering, focusing on the negative aspects, neglecting the positive part of their life.

In sum, our results showed that secure attachment relationships and high self-esteem represent protective factors for QoL of women with a diagnosis of FM, whereas the contrary emerged as regards insecure attachments and low self-esteem.

However, contrary to expectation, women’s fearful attachment style was not directly related to QoL, but only indirectly through self-esteem. Indeed, fearful attachment is characterized by both a negative model of the self and of the other; these features would put fearfully attached individuals at higher risk for psychological functioning (Vismara et al., 2019). However, being this attachment style the most disorganized, it is also the most unpredictable. In one study, for instance, fearful and dismissing attachment styles were not significantly associated with pain-related disability in patients with chronic widespread pain (Davies et al., 2009).

Limitations and future studies

Despite the interesting results regarding the predictive validity of adult attachment styles over self-esteem and QoL in women with FM, these findings should be taken with caution due to the following limitations.

First, the cross-sectional design of this study does not allow any conclusions regarding directionality of relationships. The results should be verified and supported by additional research studies, including longitudinal study.

Second, all measures were based on self-reports, so we could not prevent social desirability bias. The accuracy of self-reported attachment styles may be improved by using other measures of attachment (e.g. adult attachment interview; Main et al., 2002).

Third, physical symptoms, such as pain or fatigue, are more common in women who do not have social support (Neugebauer and Katz, 2004); among women with FM, attachment styles and self-esteem may be the stronger predictors for increased QoL, but social support could have a potential regulating effect (Jakobsson and Hallberg, 2002). Therefore, to provide a more complete model, future studies should include measures of perceived social support. Finally, the sample is limited to only FM online communities. Future research should recruit women with FM who may have requested assistance from other sources of care.

Our results suggest the need for additional research to provide integrated theoretical models to understand the mechanisms underpinning the QoL of women with a diagnosis of FM.

Regardless of these limitations, the research findings provide evidence regarding the importance of adult attachment and self-esteem in contributing to the QoL in women with a diagnosis of FM. These findings, therefore, may improve the understanding of how these psychological variables may contribute to psychological functioning of FM patients, enhancing the effectiveness of treatment in the context of this disability.

Indeed, attachment-informed interventions may constitute a useful and efficacious means to promote psychological and physical health (Mikulincer and Shaver, 2012; Palitsky et al., 2013 Pietromonaco and Beck, 2019). At the level of primary preventive programs, enhancing attachment security since infancy and childhood should be a priority to hinder malaise and favor a good QoL. At the level of secondary and tertiary prevention, identifying the individual’s attachment pattern could allow to precociously detect those at risk of adjustment difficulties to FM prior to intervention. Finally, at the level of treatment, acknowledging the individual’s attachment style may support more successful intervention since it considers the specific needs of the patient (Lewczuk et al., 2018; Meredith et al., 2008).

The study of these clinical programs may be considered one of the most promising domains of research in FM.
