AB  - Chest pain (CP) is common, frightening, and often medically unexplained. 
      Occupational psychological factors are associated with somatic pain. Personality 
      may influence both perceived working conditions and somatic health, thereby 
      confounding associations of work with health. Despite this, very few studies have 
      investigated the interplay between work factors, personality and pain. The 
      current study assessed relationships of a relatively novel work factor, human 
      resource primacy (HRP), and a personality factor known to be relevant to health, 
      dispositional optimism (Opt), with CP across two years (N = 6714). A series of 
      structural equation models (SEMs) were fitted, modeling "substantive" and 
      "confounded" relationships of psychological factors with CP. A "common latent 
      factor" (CLF) was included to account for bias by unmeasured factors that may 
      have influenced all variables (e.g. reporting bias) and the role of optimism as a 
      possible confounder of the relationship between HRP and CP was investigated 
      specifically. Independent effects of HRP and Opt on CP were observed. No effects 
      of HRP/CP on Opt were observed. Opt appeared to confound the relationship between 
      HRP and CP to some extent. However, best fit was observed for a "reciprocal" 
      model with independent lagged effects from HRP/Opt to CP as well as from CP/Opt 
      to HRP. Thus, results suggested a mutual causal dynamic between HRP and CP along 
      with an influence of Opt on both HRP and CP-implying that working conditions 
      influence the experience of chest pain while the chest pain also influences the 
      experience of working conditions. Optimistic dispositions may influence the 
      experience of both work and pain, but not to an extent that fully explains their 
      relationship. Hence, the notion that associations of HRP with CP are mere 
      artifacts of optimistic/pessimistic reporting was not supported. More likely, 
      complex reciprocal relationships exist between these factors, in which mutual 
      reinforcements occur and both vicious and virtuous cycles may result.
