The study was carried out due to the rising trend of urbanization both within the Philippines and globally. It recognized the profound transformations that urban environments manifest as they become increasingly dense and artificially dominated. It underscored the consequential impacts that these dominating features have on our daily urban lives. It emphasized the needed investigations into the perceived restorative experiences that such environments offer, particularly highlighting the challenges that urbanization and its physical manifestations pose to mental health across urban places (beyond urban parks and squares). It emphasized why other urban settings and their landscape scenes (e.g. housing, streetscapes, commercial, institutional, and transit scenes) are also worth measuring and designing diligently together with unique demographic or cultural factors to raise their restorative potentials regardless of where they are in a city or urbanizing places.
The study sought to confirm the significant roles of Environmental Visual Factors (EVFs) in influencing perceptions of restorativeness (PRP) within urban landscapes (ULS). It highlighted the notion that urban landscape scenes are comparable to natural landscape scenes to possess restorative characteristics or effects (e.g. environmental quality, complexity, affordances, fascinations, and restorativeness). Then it compared all perception differences of the five EVFs across the six USTs and different demographic factors affecting their PRP, adding to the existing literature.
The significance of the study was to inform the general public, developers, architects, urban planners, managers, designers, and policymakers with an overarching goal of enhancing the well-being and quality of life within urban settings. Despite its ambitions, the study acknowledged some limitations, including its correlational and cross-sectional design, its low ecological validity, and its specific focus on urban scene stimuli from narrowly defined locations in the Philippines, affecting its potential for generalizability.
From this point, the study of Restorative Urban Environments –in contrast to the earlier studies of “restorative (natural) environments”, has emerged in recent years. With these developments, the conceptual framework of this study draws primarily upon earlier seminal theories such as Attention Restoration Theory (ART) by Kaplan (1989), and Stress Reduction Theory (SRT) by Ulrich (1983), while also considering ideas of ecological psychology by Gibson (1979) in our proposed measurement model to help gauge and translate into the design for urban landscapes' greater restorative potentials.
Data were carefully gathered on demographic variables (e.g., gender, age, urban familiarity, education level, etc.) and stimuli ratings of the five environmental visual factors such as perceived environmental quality (PEQ), affordances (PEA), complexity (PEC), fascination (PEF), and relaxation score (PRS). All measurements were made using a 7-point Likert scale while showing variations of urban scene stimuli.
Data collection was executed through researcher-administered in-person surveys from different locations in Pangasinan, engaging a diverse pool of participants to capture perceptions of urban scenes. The survey design was carefully stratified to ensure a balanced representation of urban scenes across each survey set while mitigating participant fatigue.
The data analysis employed both descriptive and inferential statistical methods, including Structural Equation Modeling (SEM). Software tools such as G Power, AMOS, SPSS, and Excel played a crucial role in data analysis and encoding.
The collected and prepared datasets were composed of 168 participants, encompassing varying demographics. The evaluation encompassed 126 urban landscape scenes (UST) as the stimuli and was categorized into six urban scene types, yielding 3,024 observations to ensure a representative sample. Reliability analysis confirmed the internal consistency of the Perceived Restorative Potential construct with a Cronbach’s alpha of .875. However, normality tests indicated a significant deviation from a normal distribution of our data, necessitating non-parametric methods or bootstrapping for subsequent analyses. Non-parametric statistical tests and SEM in SPSS and AMOS respectively were utilized instead, due to the non-normality of our data.
Comparative analyses across different urban scene types (USTs) highlighted perceptual differences. Recreational landscape scenes were rated as the most restorative while transit landscape scenes were rated as the least, which is consistent with our predictions based on literature. Demographic factors such as gender, urban familiarity, and education level were found to have significant differences in EVFs affecting their ULS’s restorative potentials, but surprisingly not for age groups.
CONCLUSIONS & RECOMMENDATIONS
This confirmation came in the form of our proposed (ULS-PRP) measurement model, which was used in capturing PRP’s nuances of USTs and demographic factors. Notably, the study revealed significant differences in EVFs that are measuring PRP across the six USTs. Recreational landscape scenes were consistently rated highest (confirming previous studies) while transit landscape scenes were rated the lowest in terms of their PRP. Demographic factors also revealed significant differences among genders, urban familiarities such as ruralites versus urbanites, and education levels. It underscored the need for restorative urban environments that cater to a range of urban contexts and a variety of local population’s restorative needs.
Acknowledging its limitations, the author called for future research to pursue longitudinal studies, and cross-cultural comparisons, explore the current indicators as higher-order constructs, and adoption of more objective measures of restorativeness, thereby broadening our understanding of restorative urban environments and their design to raise or improve their perceived restorative potentials. This would provide more mental restoration experiences to 21st-century urban dwellers and beyond.
