“…The SSS‐8 factor structure reveals symptom clusters for gastrointestinal, pain, fatigue, and cardiopulmonary somatic expression and has shown good reliability and construct validity (Gierk et al, ). It is highly correlated with a modified version of the PHQ‐15 and demonstrates at least comparable psychometric properties (Toussaint, Kroenke, Baye, & Lourens, ). Moreover, its sensitivity to change was recently established in relation to depression, anxiety, and disability (Gierk, Kohlmann, Hagemann‐Goebel, Löwe, & Nestoriuc, ).…”

Somatic burden and perceived cognitive problems in trauma‐exposed adults with posttraumatic stress symptoms or pain

et al. 2019

Objective Posttraumatic stress disorder (PTSD) is associated with somatic and cognitive changes, which may be magnified when accompanied by persistent pain. The mechanisms of somatic sensation processing may extend to cognitive symptoms, revealing a potential generalization of impairment across cognitive and somatic domains in PTSD. We hypothesized that somatic burden would mediate relationships between PTSD, pain, and perceived cognitive impairment. Methods Two samples—360 trauma‐exposed college students and 268 mechanical Turk users—completed self‐report measures. Results Both samples revealed similar findings. There was a significant indirect effect of PTSD and pain on perceived cognitive problems through somatic burden. There remained a direct effect of PTSD symptoms. These findings indicate that in trauma‐exposed samples with pain, somatic burden rather than pain severity accounts for perceived cognitive problems. Conclusion High somatic burden may reflect an underlying appraisal about somatic cues, which extend in part to interpretation of cognitive cues.

“…For a start, it evaluates different dimensions of the disorder with fewer items. Many comparative studies suggest the use of the SSS-8 as a more efficient alternative to the original PHQ-15, especially in clinical settings or in research settings with limited assessment time to reduce the measurement burden for study participants (Toussaint, Kroenke, Baye, & Lourens, 2017). For this reason, the need for a precise and appropriate instrument for measuring the burden of physical cues is of paramount importance.…”

Somatic Symptom Disorder (SSD) refers to one or more symptoms that cause distress or a significant disruption in one's daily life and is correlated with poor Quality of Life and psychological distress, as well as an increased burden on health services. Therefore, its identification and treatment are of great importance because of the high prevalence and cost of this syndrome. The present study aimed to evaluate the factor structure, as well as the validity and reliability of the 8-Item Somatic Symptom Scale (SSS-8) in a non-clinical sample of Iranian society. Methods: The study participants included 281 individuals, who referred to Taleghani Hospital as the patients' companions. After obtaining their informed consent, the participants answered Beck anxiety inventory, general health, SSS-8, and somatic symptoms 12 questionnaires. After completing the questionnaires, the collected data were analyzed by SPSS v. 24 and LISREL software. Results: Confirmatory factor analysis indicated that gastrointestinal problems, pain, fatigue, and cardiopulmonary complaints were the general factor loadings of somatic symptoms. Besides, the 8-item Somatic Symptom Scale had good internal consistency. Regarding validity, the 8-question scale showed a positive correlation with the Beck anxiety inventory (r=0.70), general health questionnaire (r=0.70) and, somatic symptoms 12 (r=0.52). Conclusion: The findings provided preliminary support for the validity and reliability of the scores derived from the 8-item Somatic Symptom Scale. This scale can be used to evaluate the severity of somatic symptoms of patients referring to health clinics. Additionally, it is beneficial for interested researchers to investigate this disorder and its complications.

“…Clinically, these symptoms are called somatization symptoms [27,28]. Somatization is de ned as a chronic mental disorder characterized by the presence of one or more frequently changing somatic symptoms, involving multiple systems and organs of the body [29]. Those symptoms often induce patients' incorrect understanding or excessive attention, imposing a huge economic burden to the society [30].…”

Background: To develop the Patient Healthy Questionnaire-8 (PHQ-8), as a more reliable approach compared with the Somatic Symptom Scale-8 (SSS-8), evaluating somatization in patients with functional dyspepsia (FD), in which the effects of somatization assessed by these two approaches on quality of life (QoL) of FD patients were further compared. Methods: Herein, 612 FD patients completed a questionnaire involving 25 items. 8 out of 25 items were selected to develop the PHQ-8 by four methods of discrete degree, correlation coefficient, factor analysis, and Cronbach’s α coefficient. Reliability and validity of the PHQ-8 and the SSS-8 were compared by principal component and confirmatory factor analyses. The effects of somatization, depression, and anxiety on the Nepean Dyspepsia Index (NDI) for QoL were explored by Pearson’s correlation coefficient and linear regression analysis. Results: The Cronbach’s α coefficient for the PHQ-8 and the SSS-8 was 0.601 and 0.553, respectively, and the cumulative contribution rate of three extracted factors for the developed PHQ-8 and SSS-8 was 55.103% and 51.666%, respectively. Somatization evaluated by the PHQ-8 (r=0.309, P<0.001) and the SSS-8 (r=0.281, P<0.001) was found to be correlated with the NDI. The model used for the PHQ-8 showed that the values of chi-squared (χ2), root mean square residual (RMR), root mean square error of approximation (RMSEA), goodness-of-fit index (GFI), and adjusted GFI (AGFI) were 31.247, 0.01, 0.042, 0.984, and 0.967, respectively. Linear regression analysis unveiled that somatization (β=0.270, P<0.001), anxiety (β=0.163, P<0.001), and depression (β=0.136, P=0.003) assessed by the PHQ-8 were correlated with the NDI; besides, somatization (β=0.250, P<0.001), anxiety (β=0.156, P<0.001), and depression (β=0.155, P =0.001) evaluated by the SSS-8 were correlated with the NDI.Conclusions: The developed PHQ-8 showed to have a superior reliability and validity, and somatization assessed by the developed PHQ-8 showed have a greater influence on QoL of FD patients compared with the SSS-8. Our findings suggested that the developed PHQ-8 may improve fast assessment of the effects of somatization on FD patients in lieu of the SSS-8.
