School psychology journals yield hundreds of articles each year. As these journals are often evaluated based on the impact factors they produce, the aim of this study was to provide a historically complete record of the five impact factor values for the generalist school psychology journals that yield them. This study identified impact factors beginning in 1977, 20 years earlier than previously reported, and ending in 2019. Across all years and journals, the average Journal Impact Factor (JIF) was about 1.0, the average Immediacy Index was less than 0.4, the average 5-year Impact Factor was about 2.3, the average original CiteScore was 1.8, and the average new CiteScore was about 3.0. Increases in values were evident across time, and the highest recorded values across journals are held by the Journal of School Psychology (for the JIF, 5-year Impact Factor, and both CiteScore metrics) and School Psychology Review (for the Immediacy Index). Most impact factors, with the exception of the Immediacy Index, were moderately to highly correlated. The new CiteScore values were always the highest, and Immediacy Index values were always the lowest. School psychology has added journals to the list of those indexed by major databases, and these journals have increased their impact over time.

学校心理学期刊每年发表数百篇文章。由于这些期刊通常根据它们产生的影响因子进行评估，因此本研究的目的是为产生它们的通才学校心理学期刊提供五个影响因子值的历史完整记录。这项研究确定了影响因子从 1977 年开始，比之前​​报道的早 20 年，到 2019 年结束。 在所有年份和期刊中，平均期刊影响因子 (JIF) 约为 1.0，平均即时指数小于 0.4，平均值为5年影响因子2.3左右，原CiteScore平均1.8左右，新CiteScore平均3.0左右。随着时间的推移，价值的增加是明显的，并且期刊中记录的最高价值是由学校心理学杂志持有（对于 JIF、5 年影响因子和 CiteScore 指标）和学校心理学评论（对于即时指数）。除即时指数外，大多数影响因素都具有中度至高度相关性。新的 CiteScore 值始终最高，即时指数值始终最低。学校心理学已将期刊添加到主要数据库索引的列表中，并且这些期刊的影响力随着时间的推移而增加。
