Exposure to green spaces is beneficial to mental health in a variety of ways, ranging from stress reduction to increased attentiveness and elevated self-esteem. The impact of views of greenness, as opposed to direct exposure, has been examined, but the association between self-reported views and depressive symptoms is not known. The purpose of this study is to examine the relationship between views of greenness and Patient Health Questionnaire-9 (PHQ-9) score.
Questionnaire responses from 191 participants in the Health, Environment, and Action in Louisville (HEAL) study were examined. Univariate statistical analyses included Mann-Whitney U, Kruskal-Wallis, and Spearman rank tests. Inferential statistical analysis was linear regression.
Participant satisfaction with residential greenness was significantly associated with reduced PHQ-9 score (partially adjusted: linear coefficient = -0.42; 95% CI: -0.70 - -0.14; fully adjusted: linear coefficient = -0.21; 95% CI: -0.44 - 0.02). Additionally, being satisfied with local greenness was significantly associated with having views of greenness from home (linear coefficient = 1.97; 95% CI: 1.23-2.68).
Though views of greenness were not directly associated with depression, satisfaction with local greenness was associated with reduced PHQ-9 score, and having views of greenness from home was crudely associated with increased greenness satisfaction. The findings suggest urban greening interventions that focus on greenness satisfaction may be a strategy to reduce depression. Further research is necessary to better understand these relationships.
接触绿色空间对心理健康有多种益处，从减轻压力到提高注意力和增强自尊。与直接接触不同，绿色景观的影响已得到研究，但自我报告的景观与抑郁症状之间的关联尚不清楚。本研究的目的是探讨绿色景观与患者健康问卷-9（PHQ-9）评分之间的关系。
对路易斯维尔健康、环境与行动（HEAL）研究中191名参与者的问卷回复进行了分析。单变量统计分析包括曼-惠特尼U检验、克鲁斯卡尔-沃利斯检验和斯皮尔曼等级检验。推断性统计分析为线性回归。
参与者对居住环境绿色程度的满意度与较低的PHQ-9评分显著相关（部分调整：线性系数=-0.42；95%置信区间：-0.70--0.14；完全调整：线性系数=-0.21；95%置信区间：-0.44-0.02）。此外，对当地绿色程度的满意度与在家中能看到绿色景观显著相关（线性系数=1.97；95%置信区间：1.23-2.68）。
虽然绿色景观与抑郁症没有直接关联，但对当地绿色程度的满意度与较低的PHQ-9评分相关，在家中能看到绿色景观与更高的绿色程度满意度大致相关。研究结果表明，关注绿色程度满意度的城市绿化干预措施可能是减少抑郁症的一种策略。有必要进行进一步研究以更好地理解这些关系。
