In oduc ion
Academic pe o mance and i s ela ionship o adolescen smoking ha e been widely s udied. S uden s who pe o m be e
academically a e less likely o smoke, while hose whose pe o mance is weak smoke much mo e o en (B yan , Schulenbe g,
Bachman, O'Malley, &Johns on, 2000; Pennanen, Haukkala, De V ies, &Va iainen, 2011; Schnoh , K eine , Rasmussen, Due,
&Dide ichen, 2009). Poo subjec i e heal h and ac o s ela ed o well-being a e also known o be ela ed o adolescen
smoking (Bo ello-Ha baum, Haynie, Mu ay, &Ianno i, 2010; Holmen, Ba e -Conno , Holmen, &Bje me , 2000; Rius,
Fe nandez, Schia fino, Bo 
as, &Rod íguez-A alejo, 2004; Vingilis, Wade, &Seeley, 2002). Howe e , i is no well known how
school- ela ed aspec s o well-being, specifically academic well-being, ela e o smoking.
In ou s udy, academic well-being is measu ed by he concep s o school bu nou and schoolwo k engagemen , which
ha e been sugges ed o be cen al indica o s o well-being a school (Tuominen-Soini, Salmela-A o, &Niemi i a, 2012).
Bu nou was o iginally ecognized as a wo k- ela ed diso de (Maslach, Jackson, &Lei e ,1996), and in he con ex o school, i
has only been s udied o e he las decade (Walbu g, 2014). School- ela ed bu nou has been defined as a combina ion o
exhaus ion om schoolwo k, cynicism abou he meaning o school, and a sense o inadequacy as a s uden (Salmela-A o,
Kiu u, Leskinen, &Nu mi, 2009), and i can be caused by disc epancies among s uden s' in e nal esou ces, school wo k-
load and expec a ions o school esul s (Kiu u, Aunola, Nu mi, Leskinen, &Salmela-A o, 2008).
The e m “school engagemen ”has been in use since he la e 1980s, and i ypically desc ibes a mul idimensional cons uc
ha includes psychological, academic, a ec i e, cogni i e and beha io al componen s (Upadaya &Salmela-A o, 2013). I s
o igin is in wo k-li e s udies (Schau eli, Ma inez, Pin o, Salano a, &Bakke , 2002). The concep o school engagemen has
mainly been applied in No h Ame ica. Recen ly, a somewha di e en app oach, schoolwo k engagemen , was de eloped in
Eu ope ha ocuses mo e on emo ional (ene gy o schoolwo k), cogni i e (dedica ion owa d schoolwo k and a pe cep ion
ha schoolwo k is meaning ul), and beha io al (abso p ion in schoolwo k so ha ime passes quickly when s udying) di-
mensions (Upadaya &Salmela-A o, 2013). Academic well-being and academic pe o mance a e in e wined: Good academic
pe o mance is posi i ely ela ed o schoolwo k engagemen (Salmela-A o &Upadaya, 2012) and nega i ely ela ed o school
bu nou (Salmela-A o, Kiu u, e al., 2009).
The associa ion o school bu nou and schoolwo k engagemen wi h smoking has no been s udied be o e. Rega ding he
No h Ame ican concep o school engagemen , a ew s udies ha e shown ha high school engagemen can p omo e heal hy
beha io and p o ec agains heal h-comp omising beha io s, such as smoking (Ca e , McGee, Taylo , &Williams, 2007;
Wang &F ed icks, 2014). Wang and F ed icks (2014) ha e obse ed ha adolescen s wi h declines in beha io al and
emo ional engagemen wi h school had inc eased subs ance use ( obacco, alcohol, and ma ijuana).
Resea ch aims
We s udied he associa ion be ween academic well-being, measu ed by school bu nou and schoolwo k engagemen ,
and daily smoking among 14- o 17-yea -old schoolchild en in six medium-sized Eu opean ci ies. Because academic pe -

The associa ion be ween academic well-being and smoking emained when adolescen s' socioeconomic backg ound and
academic pe o mance we e con olled o . Ou esul s sugges ha school bu nou , schoolwo k engagemen , and academic

adolescen s' academic and psychological ou comes (Wang, Chow, Ho kens, &Salmela-A o, 2015).
The e a e se e al explana ions o why academic well-being and smoking a e associa ed. Fi s , he sel -sys em model (a
mo i a ional amewo k based on he sel -de e mina ion heo y) (Deci &Ryan, 2000) s a es ha he ex en o which ado-
lescen s a e engaged in school builds a mo i a ional con ex ha enables hem o deal wi h di ficul ies and ailu es in school
(Skinne &Pi ze , 2012). Consequen ly, s uden s who ail o engage o school may seek solace in p oblem beha io s, such as
smoking, which in u n may exace ba e hei disengagemen wi h school (Bachman e al., 2008). Wang and F ed icks (2014)
showed ha he associa ion be ween school engagemen and p oblem beha io is bidi ec ional: changes in adolescen s'
subs ance use a e p edic ed by hei ea ly le el o school engagemen , and changes in school engagemen a e p edic ed by
ea ly subs ance use.
Second, adolescen s' in es men s in heal h and educa ion include a ade-o be ween cu en cos s and u u e benefi s
(Fuchs, 1982). I can be assumed ha indi iduals who a e mo e p esen -o ien ed a e less likely o in es in hei u u e heal h

ademic pe o mance. In addi ion, i can be specula ed ha he associa ion be ween academic well-being and smoking eflec s
he a i udes and alues o adolescen s' amilies, which a ec s adolescen s' engagemen wi h schoolwo k and hei educa ion
and school bu nou (see, e.g., Ca e e al., 2007; S einbe g, Lambo n, Do nbusch, &Da ling, 1992).
Thi d, ou s udy analyzed he associa ions on an indi idual le el, bu he obse ed associa ions could be ein o ced by
p ocesses a a g oup le el and in ne wo ks wi hin schools. G oup-le el and ne wo k heo ies explaining adolescen smoking

academic pe o mance (Kiu u, Nu mi, Aunola, &Salmela-A o, 2009), school bu nou (Kiu u e al., 2008) and school

Ou s udy has many s eng hs. Academic well-being was measu ed wi h he same school su ey design and ins umen s in

The e a e also some limi a ions in ou s udy. We canno exclude he possibili y ha he di e ences be ween he ci ies in

Al hough he selec ed ci ies in each coun y we e a e age ones, we canno exclude he possibili y ha some o he ci ies
