As an important psychological antecedent of smartphone addiction, loneliness may have a far-reaching effect on the mental health of teenagers, especially their psychological depression. Interpersonal trust, which is an important psychological trait of individuals in social interaction, may play multiple mediating roles between loneliness and psychological depression.
Overall, 691 adolescent smartphone addicts in Henan Province, China were surveyed by a group questionnaire. Relevant data were collected via loneliness scale, psychological depression scale, and interpersonal trust scale (including overall trust, emotional trust, and reliableness). The effect of loneliness on the psychological depression of adolescent smartphone addicts was discussed via statistical analysis, and the multiple mediating roles played by interpersonal trust in this relationship were tested.
Loneliness has a significantly positive effect on the psychological depression of adolescent smartphone addicts (<0.01). Overall trust and emotional trust play a partial mediating role in the influence of loneliness on psychological depression, whereas reliableness plays a masking role in this influence relationship. Significant differences are observed in the influence of two factors-the length of smartphone use and the age-on the psychological depression of adolescent smartphone addicts (<0.01).
This study reveals the effect of loneliness on the psychological depression of adolescent smartphone addicts and the mediating role of interpersonal trust. To reduce the risk of adolescent psychological depression, psychological health intervention measures should attach importance to the enhancement of interpersonal trust, especially overall and emotional trust.
孤独作为智能手机成瘾的重要心理前因，可能对青少年的心理健康产生深远影响，尤其是他们的心理抑郁。人际信任是个体在社会交往中的重要心理特质，可能在孤独与心理抑郁之间发挥多重中介作用。
对中国河南省的691名青少年智能手机成瘾者进行了群体问卷调查。通过孤独量表、心理抑郁量表和人际信任量表（包括总体信任、情感信任和可靠性）收集相关数据。通过统计分析探讨孤独对青少年智能手机成瘾者心理抑郁的影响，并检验人际信任在这种关系中所起的多重中介作用。
孤独对青少年智能手机成瘾者的心理抑郁有显著的正向影响（<0.01）。总体信任和情感信任在孤独对心理抑郁的影响中起部分中介作用，而可靠性在这种影响关系中起掩盖作用。在智能手机使用时长和年龄这两个因素对青少年智能手机成瘾者心理抑郁的影响方面存在显著差异（<0.01）。
本研究揭示了孤独对青少年智能手机成瘾者心理抑郁的影响以及人际信任的中介作用。为降低青少年心理抑郁的风险，心理健康干预措施应重视增强人际信任，尤其是总体信任和情感信任。
