@article{ref1, title="Research on classification of individuals committing serial rapes based on their decision-making behaviors before a crime", journal="Japanese journal of criminal psychology", year="2019", author="Hirama, Kazuki and Otsuka, Yusuke and Yokota, Kaeko and Wachi, Taeko and Watanabe, Kazumi", volume="56", number="2", pages="1-14", abstract="This study aimed to (1) classify individuals committing serial rapes based on their decision-making behaviors before the criminal acts using latent class analysis, and (2) test the homology assumption that individuals displaying a similar offense style would have similar offender-characteristics. Four groups were identified: "Intruding into private spaces and raping sleeping victims," "Outdoor assault," "Non-violent approach," and "Intruding into private spaces and raping non-sleeping victims." Significant associations were found between the groups and characteristics of individuals committing these offenses. The "Intruding into private spaces and raping sleeping victims" group exhibited characteristics similar to burglars, including targeting a place prior to the crimes and intending to steal. The "Outdoor assault" group was younger and less likely to commit offenses in areas close to their residence than the others. The "Non-violent approach" group tended to be opportunistic in selecting their victims and traveled further than others did. The "Intruding into private spaces and raping non-sleeping victims" group had a lower intention to steal than the "Intruding into private spaces and raping sleeping victims" group. These results supported the homology assumption, but the associations between offenders' decision-making behaviors before committing rapes and the offender characteristics were weak to moderate in strength. 本研究の目的は(1)潜在クラス分析を用いて，犯行前の意思決定行動に基づいて連続強姦 事件の犯人を分類すること，(2)類似した犯行様式を表出する犯人は類似した犯人特徴を 有するという相同仮説を検証すること，であった。「被害者就寝時侵入接近型」，「屋外襲撃 型」，「非暴力的接近型」，「被害者非就寝時侵入接近型」の 4 つの類型が見出された。類型 と強姦事件の犯人の特徴との間に有意な関連が認められた。「被害者就寝時侵入接近型」に 分類された強姦事件の犯人は，犯行前の犯行場所の下見や，金品窃取の意図といったよう な，侵入盗犯に類似した特徴がみられた。「屋外襲撃型」に分類された強姦事件の犯人は， 他の類型と比較して，若年であることや，居住地直近では犯行を行わない傾向が認められ た。「非暴力的接近型」に分類された強姦事件の犯人は，機会的な対象選択の傾向を有し， 他の類型と比較して，より遠くまで移動している傾向にあった。「被害者非就寝時侵入接近 型」に分類された強姦事件の犯人は，「被害者就寝時侵入接近型」よりも金品窃取の意図を 有する傾向は少なかった。本研究の結果は相同仮説を支持するが，強姦事件の犯人の犯行 前の意思決定行動と，犯人の特徴との関連の強さは，小から中程度であった。
