This study aimed to explore psychometric properties of satisfaction with life scale (SWLS) and psychological capital questionnaire (PCQ-24) in the Lithuanian representative sample (n = 2003, M = 50.67, SD = 17.46). It was significant to validate instruments concerning the fact that Lithuanians’ life satisfaction surveys demonstrated divergent results depending on the assessment tools they used. This study applied the SWLS, created by Diener et al. (1985), and the PCQ-24, created by Luthans et al. (2007). The findings demonstrated the internal consistency of the SWLS instrument, evidencing it as an adequate measure to evaluate satisfaction with life (α = 0.893; TLI = 0.988; NFI = 0.997; RMSEA = 0.059 [0.033–0.088]; CFI = 0.998; SRMR = 0.0077; AVE = 0.764; CR = 0.886). The Lith-PCQ-21 analysis demonstrated the internal consistency of the instrument (α = 0.957) and good fit of the factorial structure (χ2 = 2305.383; DF = 185; TLI = 0.915; NFI = 0.920; RMSEA = 0.077 [0.075–0.080]; CFI = 0.925; SRMR = 0.0450; AVE = 0.814; CR = 0.946), evidencing the instrument as an adequate measure to evaluate psychological capital. This research confirmed that both instruments (SWLS and Lith-PCQ-21) not only have an acceptable validity, including construct validity, but they are also interrelated (χ2 = 3088.762; DF = 294; TLI = 0.913; NFI = 0.914; RMSEA = 0.070 [0.068–0.073]; CFI = 0.922; SRMR = 0.0469), and can be considered appropriate for monitoring life satisfaction and psychological capital of the Lithuanian population.
