Sense of coherence (SOC) has been associated with resilience to posttraumatic stress disorder (PTSD) and seems to be a promising factor in primary prevention of PTSD in high risk populations.
The present study evaluated the psychometric properties of the Dutch revised Sense of Coherence Scale (SOC-R) in a sample of = 527 firefighters.
To investigate the internal structure of this 13-item scale, a Mokken scale analysis and an exploratory factor analysis were conducted (i.e. parallel analysis based on MRFA).
The combined results of these analyses suggested that a one-factor solution with 10 out of 13 items was most compelling for our firefighter sample. Reliability estimates for the 10-item version increased compared to the 13-item version (13-item: α = .82, λ = .83; 10-item: α = λ = .85). As expected, the Dutch version showed positive associations with resilience (convergent validity), and low correlations with neuroticism and extraversion (discriminant validity).
The one-factor solution of the Dutch SOC-R with 10 items (excluding item 2, item 3, and item 6) is most convincing. The use of this scale might be specifically interesting regarding its potential to primary prevention of trauma-related psychopathology in high-risk samples.
连贯感（SOC）与创伤后应激障碍（PTSD）的恢复力相关，似乎是高危人群PTSD一级预防中的一个有前景的因素。
本研究在527名消防员样本中评估了荷兰修订版连贯感量表（SOC-R）的心理测量特性。
为了探究这个13个条目的量表的内部结构，进行了莫肯量表分析和探索性因素分析（即基于MRFA的平行分析）。
这些分析的综合结果表明，对于我们的消防员样本，一个包含13个条目中10个条目的单因素解决方案最具说服力。与13个条目的版本相比，10个条目的版本的信度估计有所提高（13个条目：α = 0.82，λ = 0.83；10个条目：α = λ = 0.85）。正如预期的那样，荷兰版本与恢复力呈正相关（收敛效度），与神经质和外向性的相关性较低（区分效度）。
荷兰SOC-R的10个条目的单因素解决方案（不包括第2条、第3条和第6条）最具说服力。就其在高危样本中对创伤相关精神病理学的一级预防潜力而言，使用该量表可能特别有意义。
