Functional analysis assessment procedures have proven to be highly useful in identifying variables maintaining aberrant behavior like self-injury. When successful, assessments can lead to more effective treatment than when behavioral function is unknown. Because of practical limitations, not all clinicians can conduct extensive and thorough analyses prior to treatment implementation. Although relatively brief assessments have proven successful in a number of published studies, it is unclear under what conditions those assessments would match the results of a more extended analysis. This study examined a method for assessing the behavioral function of severe self-injury in four adult participants. For each participant, the initial assessment involved analyzing within-session trends and fluctuations in rates of self-injury by plotting the frequency within each minute of a session. The results of these analyses were then compared to a set of more traditional, longer-term functional analyses conducted with each participant. Results suggested that within-session analyses are viable procedures for the assessment of self-injury. Potential benefits of within-session analyses over other brief assessments and longer-term analyses are discussed.
功能分析评估程序已被证明在识别维持诸如自我伤害等异常行为的变量方面非常有用。评估成功时，与行为功能未知时相比，能带来更有效的治疗。由于实际限制，并非所有临床医生都能在实施治疗前进行广泛而彻底的分析。尽管相对简短的评估在一些已发表的研究中已被证明是成功的，但尚不清楚在何种条件下这些评估会与更全面分析的结果相符。本研究考察了一种评估四名成年参与者严重自我伤害行为功能的方法。对于每个参与者，初始评估包括通过绘制会话中每分钟的频率来分析会话期间自我伤害发生率的趋势和波动。然后将这些分析结果与对每个参与者进行的一组更传统、更长期的功能分析结果进行比较。结果表明，会话期间分析是评估自我伤害的可行程序。文中讨论了会话期间分析相对于其他简短评估和长期分析的潜在益处。
