This study aimed to explore psychometric properties of satisfaction with life scale (SWLS) and psychological capital questionnaire (PCQ-24) in the Lithuanian representative sample ( = 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 (χ = 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 (χ = 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.
本研究旨在探索生活满意度量表（SWLS）和心理资本问卷（PCQ-24）在立陶宛代表性样本中的心理测量特性（n=2003，M=50.67，SD=17.46）。由于立陶宛人的生活满意度调查结果因使用的评估工具而异，因此验证这些工具的有效性非常重要。本研究采用了 Diener 等人（1985）创建的 SWLS 和 Luthans 等人（2007）创建的 PCQ-24。研究结果表明，SWLS 工具具有内部一致性，可作为评估生活满意度的适当工具（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）。Lith-PCQ-21 分析表明，该工具具有内部一致性（α=0.957）和良好的因子结构拟合（χ=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），表明该工具可作为评估心理资本的适当工具。本研究证实，这两种工具（SWLS 和 Lith-PCQ-21）不仅具有可接受的有效性，包括构念效度，而且它们之间还具有相关性（χ=3088.762；DF=294；TLI=0.913；NFI=0.914；RMSEA=0.070[0.068-0.073]；CFI=0.922；SRMR=0.0469），可用于监测立陶宛人口的生活满意度和心理资本。
